List of Top JavaScript Frameworks 2020 For Front End Development
JavaScript is defining the future of the tech world with its wide genre of competent frameworks, which are capable of accelerating the development of applications in many ways. How to choose a certain framework in JavaScript is based on the company’s goals, project requirements and how certain frameworks can be used in different scenarios.
JavaScript, one of the most surreal and beautiful programming languages, enwrapped by the intriguing fact that even though it is named “Java” Script, it doesn’t have any association with Java. In mid-1995, when JavaScript came into existence it was disguised as the name Mocha and later it was named as “LiveScript” and when Netscape and Sun did a license agreement it was finally renamed to “JavaScript”. Nobody had even imagined in its initial form that it would be such a revolutionary programming language and would be entitled as one of the major languages to learn. The world is pacing fast with the ever-changing technology and programming languages being the pillar of technology. JavaScript is surely defining the future with its compelling and competent frameworks.
What are the Frameworks?
In general, a framework is a prototype or conceptual structure intended to serve as a support or guide for the building of something that expands the structure into something useful. According to Wikipedia ” A software framework is an abstraction in which software providing generic functionality can be selectively changed by additional user-written code, thus providing application-specific software.”
JavaScript web frameworks are cheat codes for quick web application development. They serve as a skeletal frame for single page application development and allows developers to worry less about code structure or maintenance and help them in focusing more on the creation of complex interface elements and expand opportunities of JS and plain HTML.
So, Which frameworks of JavaScript are most popular and why?
Below is the list of a few Javascript frameworks:
1. AngularJS- AngularJS is an open-source framework used in frontend and is maintained by Google. It is mainly used to subside and sort the problems encountered while creating single-page applications usually have, as it simplifies both development and testing of such application by providing a framework for client-side model view controller (MVC) and model view-view model (MVVM) architectures. For now, it is known to be the most used JavaScript framework for single-page applications and have the largest community of developers.
2. ReactJS- ReactJS camouflage itself to be JS framework but it is more of an open-source JS library, which has huge names like Facebook and Instagram behind it. React was built by a software engineer at Facebook. In 2011, it was first deployed on Facebook’s newsfeed and later on Instagram in 2012. React Js emerges in an ecosystem of complete frameworks, but it’s just the view. In MVC(Mobile-View-Controller) pattern, React.js acts as “V” and can be smoothly integrated with any architecture.
A fully functional dynamic application can’t be built with React alone. Recently, On April 18th 2017, Facebook announced a new core algorithm of React framework library for building user interface named React Fiber, which is said to be the foundation for future development and improvement of ReactJS.
3. Ember JS- A few years back, in 2015, EmberJs was considered to be the best framework leaving React and AngularJS behind. It does two-way data binding as same as AngularJS keeping both view and model in sync for all the time. Emberjs is commonly used for complex feature-rich web applications and website. LinkedIn, Netflix, Chipotle, Blue Apron, Nordstrom are one of the few of the top names that have incorporated EmberJS.
What works in its favour is that it is easy to learn and have many tutorials online which helps to learn it with ease.
4. Vue.Js- Vue.js is considered to be one of the best solutions for cross-platform development. The development of Vue.Js is considered by taking the best qualities from Angular, React and Ember such as Vue.js offers two-way data binding (same as in AngularJS), server-side rendering (like in Angular2 and ReactJS), Vue-CLI (backbone tool for quick start) and optional JSX support. and all the altering flaws in prior three.
5. MeteorJS- MeteorJS is a free and open-source framework, which is well-equipped with tons of features for back-end development, front-end rendering, DB(database) management and business logic. Being a full-stack platform, it has the quality that its name suggests which is being fast. If you’re looking to rapidly develop smaller, reactive applications on the Node.js platform, Meteor is definitely an excellent choice.
Due to its modular structure, all the packages and libraries can be used at a high pace. In terms of performance, all the changes in the database are transmitted to the UI in the shortest time possible and in conversely with no evident time losses caused by different languages or server response time.
The consideration of a JavaScript framework is based on the company’s goals, project requirements and how certain frameworks can be used in certain scenarios. JavaScript is portraying the whole new depiction of the future of technology as it backs the prompt development and prototyping.
These frameworks and libraries have already reshaped the way how JS collaborates with HTML and CSS to compile views both in browsers and now even on native platforms.

Full Stack Angular Java Developer
What if we told you that developers who work with one programming language or technology may prefer a certain UI framework? Stack Overflow broke developers into groups based on the tag they most visit and examined the percentage of traffic that goes to each of these frameworks.
“The JavaScript ecosystem is richer than ever, and even the most full stack Angular Java experienced developer can start to hesitate when considering the multitude of options available at every stage,” according to The State of JavaScript 2017.
They are not wrong, that’s for sure. A lot of things are happening in the JavaScript world right now and we’re happy to help by showcasing developers’ experiences with different libraries and frameworks. As a matter of fact, the new JAX Magazine issue is all about the JavaScript universe. You can grab your free copy now.
Stack Overflow’s Ian Allen set out to show that “JavaScript UI frameworks and libraries work in cycles.” He used Stack Overflow Trends to see how popular Angular, React, Vue.js, Backbone, Knockout, and Ember are and when their popularity started and/or peaked. He concluded that there seems to be two major phases in JavaScript framework usage:
a quick ascent, as the framework gains popularity
a slightly less quick but steady decline as developers adopt newer technologies
SEE ALSO: “Angular’s refocusing on the enterprise market has left an opening for React to gain ground”
“There are various factors that may go into a developer’s use of one particular front-end framework or another,” Ian wrote in the blog post. “Developers who primarily work with one programming language or technology may be more inclined to choose a certain UI framework.”
He broke developers into groups based on the tag they most visit, and for each group examined the percentage of traffic that goes to each of these frameworks.
Frameworks used along with programming technologies
It seems that developers who primarily work with Java are more inclined to choose Angular, whereas React is more popular with Node.js, and Python developers. Node.js developers are also giving Vue.js some love but not as much as PHP developers.
SEE ALSO: JAX Magazine is out: The darlings of the JavaScript world
Hottest freelance skills: React.js secures Top 5 spot
The number of libraries and frameworks could easily overwhelm anyone so if you’re still on the lookout for the perfect framework and/or library, let’s see what’s trendy these days.
If we look at Upwork’s latest Skills Index, React.js may not be No.1 but it’s important enough (number 5) to be included in the top 5 fastest-growing skills (Q3 2017) in the US. AngularJS development didn’t make the Top 10 freelance skills list but it did occupy a decent position (number 12).
However, this might not be so surprising, if you ask Laurie Voss, co-founder and COO of npm. In a recent interview, he said:
React is growing faster than JavaScript in general, while Angular is basically keeping pace. The difference can probably be explained in terms of “what would a new developer pick?” since that’s where new growth of frameworks tends to come from.

Why do JavaScript enthusiasts prefer Vue.js web development?
Vue.js is an open-source Model View Viewmodel  JavaScript framework used to create UIs and single-page applications. Its latest version is Vue.js 2.6 and it is the second most loved framework as per Stack Overflow Developer Survey 2019. In fact, the number of developers who used Vue and would use it again grew from 19.6% in 2017 to 28.8% in 2018, according to the State of JavaScript survey.

React JS compare to Angular 2
React JS compared to Angular 2
A while back, we wrote a piece comparing Angular 2 and react. In that piece, we outlined the advantages and disadvantages of different frameworks and offered recommendations for what to select in 2017 depending on the situation. So, how is the front-end garden faring in 2018?
Tumblr media
Because JavaScript frameworks are evolving so quickly, today's versions of Angular, ReactJS, and another contender on the market, Vue.js, are regularly updated. Let's take a look at the demand as it has been reflected in Google Trends over the past five years. Angular, React, and Vue.js are each represented by a blue, red, and yellow line.
The graph demonstrates that between 2013 and 2014, there was a slight variation in the number of React and Angular questions. Then, we observe that the difference between them grew for a brief time. From the middle of 2016, these demands were balanced, and
React began to expand and become closer to meeting Angular needs
. Although the Vue.js framework was still not very well known, it was slightly increasing its market share among frameworks, indicating the potential for future growth. In recent years, Angular and React have become nearly evenly matched, making them the most practical front-end frameworks available.
ReactJS's benefits and drawbacks
ReactJS is a JavaScript toolkit that Facebook released as open source in 2013 and is excellent for creating large web apps with often changing data.
Advantages of ReactJS
simple to learn. Due to its straightforward syntax, React is significantly simpler to learn. All engineers need to do is recall their HTML authoring abilities. No need to fully understand TypeScript, as with Angular.
The highest degree of reactivity and flexibility.
Virtual DOM (document object model) enables the organization of documents in HTML, XHTML, or XML forms into a tree from which web browsers may parse various web app components more easily.
When used with ES6/7, ReactJS can handle heavy loads.
on a simple basis.
With this type of data flow, downward data binding means that the child item cannot impact parent data.
A JavaScript framework that is completely open-source and receives regular updates and enhancements thanks to the efforts of developers around the world
Lightweight due to the ease with which the user-side data processing can be simultaneously represented on the server side.
The majority of the migration procedure may be automated thanks to Facebook's "codewords," which make the process in general fairly simple.
Limitations of ReactJS
Lack of formal documentation — due to ReactJS's lightning-fast development, there is no room for the necessary documentation, which is now somewhat disorganized due to developers' ad hoc contributions.
React is agnostic, therefore developers occasionally have too many options.
React JS demands an extensive understanding of how to integrate user interfaces into the MVC framework because it takes a long time to grasp.
Facebook, Instagram, Netflix, New York Times, Yahoo, Khan Academy, Whatsapp, Codecademy, Dropbox, Airbnb, Asana, Atlassian, Intercom, and Microsoft are among the companies that employ ReactJS.
Angular 2's benefits and drawbacks
The 2009-founded, super-heroic Angular JavaScript MVVM framework is fantastic for creating incredibly interactive and incredibly interactive web applications.
Angular 2 advantages include:
Improved RXJS, a quicker compilation time (under 3 seconds), and a new HttpClient launch are some of the new improvements.
Developer developers can obtain all the information they need from thorough documentation without having to consult their colleagues. This calls for extra study time, though.
Two-way data binding allows for unique app behavior and reduces the possibility of errors.
Developers can work independently on the same app area utilizing the same set of data thanks to MVVM (Model-View-ViewModel).
dependency injection of features about modules and modularity in general about parts.
Limitations of Angular 2:
The intricate syntax results from the original Angular framework. However, TypeScript 2.4, which is used by Angular 5, is the easiest to learn of the bunch.
Migration issues may arise while switching from an earlier version to the most recent version.
Upwork, Freelancer, Udemy, YouTube, Paypal, Nike, Google, Telegram, Weather, iStockphoto, AWS, and Crunchbase are among businesses that employ Angular 5.

Bootstrap
Bootstrap
Bootstrap is a free and open-source CSS framework directed at responsive, mobile-first front-end web development. It contains HTML, CSS and (optionally) JavaScript-based design templates for typography, forms, buttons, navigation, and other interface components.
As of August 2021, Bootstrap is the tenth most starred project on GitHub, with over 152,000 stars, behind freeCodeCamp (over 328,000 stars), Vue.js framework, React library, TensorFlow and others.
Early beginnings
Bootstrap, originally named Twitter Blueprint, was developed by Mark Otto and Jacob Thornton at Twitter as a framework to encourage consistency across internal tools. Before Bootstrap, various libraries were used for interface development, which led to inconsistencies and a high maintenance burden. According to Twitter developer Mark Otto
Bootstrap 2
On January 31, 2012, Bootstrap 2 was released, which added built-in support for Glyphicons, several new components, as well as changes to many of the existing components. This version supports responsive web design, meaning the layout of web pages adjusts dynamically, taking into account the characteristics of the device used (whether desktop, tablet, mobile phone.
Bootstrap 3
On August 19, 2013, Bootstrap 3, was released. It redesigned components to use flat design and a mobile first approach. Bootstrap 3 features new plugin system with namespaced events. Bootstrap 3 dropped Internet Explorer 7 and Firefox 3.6 support, but there is an optional polyfil for these browsers.

VuexをTypeScriptで利用するのに悩んだ https://ift.tt/2MOnODr
概要
Vue.jsをTypeScriptで開発する際にVuexを利用するのにしっくりくる実装方法を模索中で、いくつか方法を試してみました。
GitHubに利用したプロジェクトをUPしています。実際に試してみたい方どうぞ^^
https://github.com/kai-kou/vue-js-typescript-vuex
準備
ここではDockerを利用して環境構築していますが、ローカルで構築してもらってもOKです。
> mkdir 任意のディレクトリ > cd 任意のディレクトリ > vi Dockerfile > vi docker-compose.yml
Dockerfile
FROM node:10.8.0-stretch RUN npm install --global @vue/cli WORKDIR /projects
docker-compose.yml
version: '3' services: app: build: . ports: - "8080:8080" volumes: - ".:/projects" tty: true
> docker-compose up -d > docker-compose exec app bash
コンテナ内
> vue create app Vue CLI v3.0.1 ? Please pick a preset: Manually select features ? Check the features needed for your project: Babel, TS, Vuex, Linter, Unit ? Use class-style component syntax? Yes ? Use Babel alongside TypeScript for auto-detected polyfills? Yes ? Pick a linter / formatter config: TSLint ? Pick additional lint features: Lint on save ? Pick a unit testing solution: Mocha ? Where do you prefer placing config for Babel, PostCSS, ESLint, etc.? In dedicated config files ? Save this as a preset for future projects? No ? Pick the package manager to use when installing dependencies: (Use arrow keys) ❯ Use Yarn Use NPM
コンテナ内
> cd app > yarn serve
これで実装の準備が整いました。
Vue-Cli標準
vue create コマンドでプロジェクトを作成するとsrc直下にstore.tsが作成されているので、そこに実装をいれて利用するパターンです。
stateにcounter ってのを持っていて、それをインクリメントするアクションがあるだけです。
src/store.ts
import Vue from 'vue'; import Vuex from 'vuex'; Vue.use(Vuex); interface State { conuter: number; } export default new Vuex.Store({ state: { conuter: 0, } as State, getters: { getCounter: (state, getters) => () => { return state.conuter; }, }, mutations: { increment(state, payload) { state.conuter += 1; }, }, actions: { incrementAction(context) { context.commit('increment'); }, }, });
App.vueで使ってみます。 超適当ですが、画像にclickイベント定義して、HelloWorldコンポーネントでstateに定義しているcounter を表示してます。
src/App.vue
<template> <div id="app"> <img alt="Vue logo" src="./assets/logo.png" @click="increment"> <HelloWorld :msg="`Welcome to Your Vue.js + TypeScript App ${this.counter}`"/> </div> </template> <script lang="ts"> import { Component, Vue } from 'vue-property-decorator'; import HelloWorld from './components/HelloWorld.vue'; @Component({ components: { HelloWorld, }, }) export default class App extends Vue { private get counter(): number { return this.$store.getters.getCounter(); } private increment(): void { this.$store.dispatch('incrementAction'); } } </script> (略)
ブラウザで確認すると、画像をクリックするとcounterがインクリメントするのが、確認できます。
Tumblr media
気になる点
実装はシンプルで良いのですが、規模が大きくなってくると、store.tsが肥大化してくるのが目に見えます。辛い。
this.$store を利用するので、メソッド名などを間違えていても実行時にしかエラーにならないので、せっかくTypeScript使っているのになーです。
src/App.vue
export default class App extends Vue { private get counter(): number { return this.$store.getters.getCounter2(); // 実行時にエラー } private increment(): void { this.$store.dispatch('incrementAction2'); // 実行時にエラー } }
vuex-type-helperを利用する
下記記事で紹介されていたvuex-type-helperを利用してみます。
Vue.js + Vuex + TypeScript を試行錯誤してみた https://logs.utahta.com/blog/2017/09/02/110000
ktsn/vuex-type-helper https://github.com/ktsn/vuex-type-helper
vuex-type-helperとvuex-classってのを追加します。
コンテナ内
> yarn add vuex-type-helper vuex-class
storeの実装を追加します。ここではモジュール化してみます。
> mkdir -pv store2/modules > touch store2/index.ts > touch store2/modules/app.ts
store2/index.ts
import Vue from 'vue'; import Vuex from 'vuex'; import { app } from '@/store2/modules/app'; Vue.use(Vuex); export default new Vuex.Store({ modules: { app, }, });
store2/modules/app.ts
import Vuex, { createNamespacedHelpers } from 'vuex'; import { DefineActions, DefineGetters, DefineMutations } from 'vuex-type-helper'; export interface State { counter: number; } export interface Getters { counter: number; } export interface Mutations { increment: {}; } export interface Actions { incrementAction: {}; } export const state: State = { counter: 0, }; export const getters: DefineGetters<Getters, State> = { counter: (state) => state.counter, }; export const mutations: DefineMutations<Mutations, State> = { increment(state, {}) { state.counter += 1; }, }; export const actions: DefineActions<Actions, State, Mutations, Getters> = { incrementAction({ commit }, payload) { commit('increment', payload); }, }; export const { mapState, mapGetters, mapMutations, mapActions, } = createNamespacedHelpers<State, Getters, Mutations, Actions>('app'); export const app = { namespaced: true, state, getters, mutations, actions, };
利用できるようにmain.tsとApp.vueを編集します。
src/main.ts
import Vue from 'vue'; import App from './App.vue'; -import store from './store'; +import store from './store2';
src/App.vue
import { Component, Vue } from 'vue-property-decorator'; import HelloWorld from './components/HelloWorld.vue'; import { Getter } from 'vuex-class'; import * as app from './store2/modules/app'; @Component({ components: { HelloWorld, }, methods: { ...app.mapActions(['incrementAction']), }, }) export default class App extends Vue { @Getter('app/counter') private counter!: number; private incrementAction!: (payload: {}) => void; private increment(): void { this.incrementAction({}); } } (略)
はい。
気になる点
こちらの利点としてはモジュール化しやすい点と、アクション名を間違えてたときにビルドエラー吐いてくれる点でしょうか。
メソッド名間違い
methods: { ...app.mapActions(['incrementAction2']), },
エラー出してくれる
Argument of type '"incrementAction2"[]' is not assignable to parameter of type '"incrementAction"[]'. Type '"incrementAction2"' is not assignable to type '"incrementAction"'.
getterで間違ってる場合は、ブラウザ側でエラーになります。惜しい。
プロパティ名間違い
@Getter('app/counter2') private counter!: number;
ブラウザでエラー
Tumblr media
vuex-classを利用するとActionなんかも以下のような定義ができるけれど、getterと同様にメソッド名間違いがブラウザでしか検知できないので、微妙。
vuex-classでAction定義
@Action('app/incrementAction') private incrementAction!: (payload: {}) => void;
うーん。独自実装いれたらもっとブラウザエラーを回避できそうですが、どこまで実装しようか悩ましいところです。

Top 4 Cross-Platform App Development Frameworks
Top 4 Cross-Platform App Development Frameworks
Keywords- Best mobile app development companies in India, Mobile app development company in chennai
Cross-platform app development frameworks allow the developers to build an app with one-time coding. The apps developed on such platforms do not require much change and can run on multiple platforms. Many cross-platform development frameworks help developers build apps rich in quality in the present situation. A cross-platform mobile app is a simple app without many complex animations and functions. Today, there are several cross-platform app development frameworks available, allowing the developers to build several apps for businesses.
4 Cross-Platform App Development Frameworks:
1.      React Native: React Native is created by Facebook Inc. in early 2015. React Native combines the best features on JavaScript and React.JS while building an app. It does not use Webview and HTML technologies. They have platform components in JSX and CSS like polyfills instead of CSS. It allows creating an app for various platforms like Android, Android TV, iOS, macOS, tvOS, Web, Windows, and UWP. This framework focuses on UI and helps the developer to create a highly responsive user interface.
2.      Xamarin: Developed in 2011 as an independent platform but later acquired by Microsoft. The framework is based on the open-source implementation of the .NET platform – Mono. It includes its own C# compiler, runtime and core .NET libraries. Here, the programs are written in C# to run on operating systems like Unix systems, Mac OS, etc. The apps developed on this platform does not run on Windows. It is a free and open-source network with a large community. Xamarin is pretty simple to use due to C# and .NET environment.
3.      NativeScript: It is an open-source cross-platform that uses programming languages like XML, CSS, JavaScript. NativeScript apps can be built on any language which can be converted to JavaScript. It also supports Angular JS and Vue.js. NativeScript builds app for Andriod and IOS platforms. For using NativeScript, you need not download any plugins, unlike other cross-platform frameworks. It does not use WebView; instead, it uses a native platform rendering engine to provide a truly native user interface. To use platform-based APIs, you need not have to know about Java or Objective-C because you can write the programming in JavaScript. In India, several mobile app development companies build apps for businesses. Some of the best mobile app development companies in Chennai help you build app through NativeScript and other development frameworks.
4.      Flutter: Flutter was developed by Google in May 2017. It is also a free open-source, cross-platform framework that allows the developers apps with one array of code. It does not use JavaScript at all; instead, it uses Dart programming language. Dart can help you write much more structured program code, and as a result, you can create more complex applications. Flutter's Hot-Reload feature is one of the best features that distinguish it from the frameworks. It allows the developers to make changes in the code and observe the results in real-time. It caters to different platforms like Android, iOS, etc. It is the only framework where you can build apps for Fuchsia OS. It has its own graphics engine, and the apps created on Flutter are better in performance than apps built on other cross-platform frameworks. The best mobile app development companies in India are adopting this framework to make better and complex apps for businesses.

JS完全に理解した……(し て ま せ ん)  見出しはエンジニア界隈でお馴染みのダニング=クルーガー曲線のアレでございます。2020年6月に出たばかりの最新のJS本を読んだので書評です。  570ページ余りの分厚さで電子版もあり。著者はECMAScriptの仕様にも関わっているazuさん、Angular日本ユーザー会代表のSuguru Inatomiさんと強力な布陣。ES2015(ES6)以降も進化を続けるJavaScriptについて、完全にES6をベースにしたモダンな入門書となっています。  コンテンツはGitHubで管理されてオープンソースとして執筆され、様々な人がコントリビュートした結果が反映される面白い作り方になっています。Web版もすべて無料で参照できるのですが、こういう体系的な情報はまとまった本で学ぶことにしているので電子版で読みました。  僕も2017-2018年ごろに掛けてJS&フロントエンド技術には再入門して、あれこれ本を読んだり3つの有力フレームワークを学んだり比較した結果を【JavaScript】3大フレームワーク Angular, React, Vue.jsを比べてみよう (2018年4月) - Rのつく財団入り口の記事にしたらなんか沢山アクセスがあったり、実案件でも実戦投入してきました。 規模の大きい開発にNode.jsビルドシステムを導入してリファクタしたり、用が足りると判断した案件では伝統のjQueryを使ったり、最近は見た目重視の案件にVue.jsを投入したりしています。社内の周囲ではJSもできるマンという感じになっています。  では(本来の意味で)JSを完全に理解しているか……というとけっこう怪しくて、使ってない構文もあればまだまだ理解しきれていないところもあります。またエンプラ世界の辛みで2020年の今もIE11の亡霊がなかなか絶滅してくれず、泣く泣くIE11でも動く古い書き方で留めておいたりすることもあります。(まあBabelとかもありますが。)  最近のフロントエンド人気にあやかってググっても大量に出てくるJavaScript情報でも、うっかり油断すると変数宣言が未だにvarだったり、古い情報や既に正しくなくなっている情報も出てきます。まとまった信頼できる情報を手元に置いておきたいなあとはよく思っていました。  『改訂新版JavaScript本格入門』という良本があるのですが、物理本を会社に残したままテレワークに突入してしまったので、これを機に改めて読んでみることにしました。 第1部 基本文法 constは再代入できないけどオブジェクトだと中のプロパティは変えられるので厳密には定数ではない、nullとundefined の比較……などやっぱり頭から抜けてた情報がありました。デバッグ方法やエラーの種類も書いてあるのがいいですね。 第7章 暗黙的な型変換 ここを読んでこれからは厳密等価演算子の === を常に使おうと固く決意して、今のプロジェクトのコードにも適用しました。(笑) falsyになる6種類の分類も雰囲気でやってたので明示的な解説がありがたいです。 第8章 関数と宣言、第9章 文と式 8章はよく忘れがちなアロー関数の話、9章は文と式は別で文はセミコロン必要という話。 全体的に本書はコード例も簡潔で良いですね。そしてつくづくJavaScriptの初期仕様はバグを出しやすい曖昧さがあちこちにあったんだなあと思います。 第10章 条件分岐 If文の中に変数を書くとfalsyかどうかで判定する。ということは「文字列がundefinedでもnullでも空文字でもない」を判定する時は if (varName) {....}だけでいいのか...! ネタ画像ですいません 第11章 ループと反復処理 配列の forEach, filter, someの後はコールバック関数であれば良いのだから、アロー関数にしなければもしやES2015以前のIE11用コードでも使えるのかな...? などなど、曖昧に使っていたところにけっこう知識の抜けがありそました。 第12章 オブジェクト JSでよく出てくるオブジェクトのおさらい。厳密にはキーと値の組のことをまとめて「プロパティ」と呼ぶのは地味に知らなかった...! キーの存在確認はundefinedとの比較より、in演算子かhasOwnPropertyメソッドの方が安全なんですね。 Object.keys以外にもES2017で列挙メソッドが増えたり、進化が続いているなあという印象です。 第13章 プロトタイプオブジェクト 普段目にしないのでよく忘れる、Object.prototypeというプロパティにオブジェクトが入っており組み込みオブジェクトはみんなこれを継承しているから組み込み関数が使えるよという話。例が簡潔かつ豊富で判りやすいです。 第14章 配列 よく出てくる配列の話。配列もオブジェクトの一種だけどArray.isArrayは配列かどうかだけを判定してくれるんですねえ。 findIndex, find, includesなどES2015以降の便利メソッドも増えているので、意識して新しい方を使っていかなければと思いました。IE11さえ、IE11さえいなければ...(呪呪呪呪呪) 列挙されると分かる、filterやreduceなどコールバック関数が必要な高階関数群。Array-likeなオブジェクトもあったりしてややこしい。破壊的メソッドと非破壊適用メソッドも名前から区別できれば良いのですが、そうもいかないですね。 第15章 文字列 頻出の文字列操作のあたり。sliceメソッドとsubstringメソッドの挙動が微妙に違うなど、なんでこういう言語仕様にしたんだろうなあと思います。JSにはいままでString#srartWithがなかったなど細かな発見もありました。 正規表現は普段はリテラルから、変数を使う場合はRegRxpクラスのコンストラクタから使うとGood。 match, exec, testと動作が少しづつ違う。コードの意図を判りやすくするにはStringクラスのメソッド群、柔軟な操作には正規表現を。 あまり使わないので曖昧になって��正規表現周りが整理できました。タグつきテンプレート関数は普段使わないのであまり理解できず……。 文字列の内部処理。絵文字も入ってくると文字コードの世界は奥が深い...! 第17章 ラッパーオブジェクト プリミティブ型の値にも裏で自動的に変換が掛かるので文字列からStringクラスのメソッドが呼べるんだよ、という話。JSでは常にリテラルを使うのがお作法。JSは「すべてがオブジェクトのように見える」言語だという話は納得です。 第18章 関数とスコープ 外側のスコープを順に見ていくのを「スコープチェーン」と呼ぶのは改めて知りました。 そしてJS特有の巻き上げの話。varによる変数宣言は宣言だけがより外側の関数かグローバルスコープに移動するので、この不思議な動きをするんですね。つくづくES2015までの世界のインターネッツのwebサイト群はよくこんな仕様の言語で壊れずに動いてたなと思います。 そして関数が状態をもったように振る舞ってくれるクロージャーの理解のカギは、JSの静的スコープとメモリ管理の仕組みである。この辺も難しいのですが、サンプルが明確なのでなるほど...!となります。 第19章 関数とthis JSでよくハマるthisの挙動の話がしっかり解決してあります。 普通に関数宣言したらundefined 、オブジェクトの中のメソッドから呼ぶとベースオブジェクトになる。 実はcall, apply, bindという明示的にthisを指定できる関数があるのは完全に忘れていました。 そしてよく問題になる、コールバック関数の中でthisを使う話。対処法は組み込み関数に引数として渡せるなら渡す、一時変数へ代入しておくというのはよく実際の開発時もやりますね。 そしてES2015以降のオススメが出ましたアロー関数で、常に外側の関数のthis を指すから分かりやすい...というもの。例をもとに明確に書いていてありがたいです。ES2015の仕様を策定した偉い人も通常の関数ではthisを使うべきではないと述べているそうで、このへんJSは難儀な言語だなぁと改めて思います。 第20章 クラス JSでも遂に書けるようになったクラス構文やsetter, getter。staticメソッドも書けるというはよく知りませんでした。 そしてclass 構文で書いたプロトタイプメソッドより、個々のインスタンスのコンストラクタに書いたインスタンスメソッドの方が優先されるというあたりもJS独特です。 そしてこれも独特なプロトタイプオブジェクトの話へ。インスタンスからクラスで定義したメソッドを呼べるのは、内部的にprototypeへの参照を持っているから。なるほどChromeの開発者ツールで見ると時々出てくる __proto__ はこの辺と関係しているんですね。 第21章 例外処理 Errorオブジェクトの種類などが明確に説明されています。 第22章 非同期処理: コールバック /Promise/Async Function JSでは非同期処理は「並行処理」、メインスレッドの中で切り替えながら行われる。名前はよく聞くWeb Worker APIの完全な非同期処理は「並列処理」で両者は違うもの。このへん日本語が混乱しがちです。 非同期処理では例外をキャッチできないのは実は知りませんでした。 そして今までのJSでコールバック関数の第1,2引数に渡るものでエラーを判別していたものは「エラーファーストコールバックスタイル」とちゃんと名前がついていました。 そして非同期処理をより簡単に表現しよう...と導入されたPromiseの話。予め成功時、失敗時の動きを関数で定義して引数で渡して実行することができます。メソッドチェーンは本書ではPromiseチェーンと呼んで三重、四重の処理をしたり。 本書の例は全体的に分かりやすいのですが、構文に慣れていないせいかPromise周りは難しく感じました。 非同期処理すべてが終わったら先に行く Promise.all, 一番最初に終わった処理だけ採用のPromise.race, そしてES2017から使えるようになる、より簡潔に書けるようになる async function 。 難しいですがこのへんは極めると色々応用が効きそうです。Promiseについてだけ別の本をPDFで作ったそうですが、確かに奥がかなり深そうです。 第23章 Map/Set JSにありそうで今までなかったMapとSet。オブジェクトを使う場合との比較など。使い方は他の言語とほぼ同じです。 JSON.stringifyに第2引数以降があるのはよく知りませんでした。 第25章 Date 言語仕様の分だけだと足りないところもあるDate周り。なるほど機能不足を補うために時々聞くライブラリのmoment.jsなどが出てくるのですね。 第1部の終わりにはモジュール機能の話、そしてJSの仕様が2015年以降毎年新しくなって進化している話が述べられています。 世の中の情報が膨大で間違っていることもあるので、適切な調べ方をもっておくことが大切...というのはなるほどなと思います。次の第2部は3つのユースケースを題材にした実際の開発での実践編です。 第29章 アプリケーション開発の準備〜第30章 ユースケース: Ajax通信 Node.jsを入れたりよくやる準備をしていざ開発へ。 最終的にはローカルで立てたサーバーで画面に入力したidを元に、GitHubのAPIと通信してユーザー情報を取得して表示する画面を作っていきます。最初はサンプルコードがイベントの中に長い処理がすっぽり入ってかなり不格好ですが、どんどんリファクタリングされて分割され綺麗に整っていきます。 通信はES6以降のFetch APIを使っていて、ここもついjQueryのメソッドを使っちゃったりするので従来のやり方から切り替えないとなと思いました。 そしてPromiseを使って実装すると、前の処理の結果をラップして次の処理に渡していけるんですね。さらにasync functionを使って書くとサーバーサイドの言語の順次処理のように簡潔に書けます。同期処理と非同期処理が両方あっても連鎖できるのがポイントですね。このへん実際使って慣れていかないとなあと思いました。 第31章 ユースケース: Node.jsでCLIアプリケーション 拡張子.mdのファイルを読み込んでHTMLを出力するコンソールアプリケーションを作っていきます。追加するライブラリはcommander, markedなど。オプションをデフォルト設定して起動時の指定を有線する所などは他の言語と同じ感じ。この章の例は分かりやすいですね。 外部ファイルの読み込みはES moduleの標準でなくCommonJSモジュールを使っていて一般的にはどっちが多いのだろうと思いました。 第32章 ユースケース: Todoアプリケーション JSの例でよく出てくるToDoアプリを開発します。最初は画面をそのまま実装し、DOM要素に直接値を持たせると限界があり、またどんどんイベントを登録していくと複雑になる一方である……と従来のやり方の問題点を提示します。 その後は状態やデータを別に持つModelクラスに分離するやり方を導入します。 さらにフロントエンドでよくあるObserverの考え方を導入、EventEmitterクラスを作ります。これも分かると何のことはなくてイベント名、コールバック関数の組で処理を貯めてSetに保持、外側からイベント発生時に emit されたら貯めてある中からコールバック関数を取り出して発動させるだけなんですね。これがModelクラスの親になるのが肝か。 最終的にはHTMLを描画する部分もViewクラスに切り出して、MVVMアーキテクチャ的なクラス構成になります。なんとなく思想的にはJSフレームワークのVue.jsに近い感じがしました。ViewクラスでDOM要素を描画しているところはReactっぽくもあります。メイン処理のAppクラスが役割的にはViewModelに近いような形でしょうか。 最終的にはリファクタリングして綺麗になるのですが、ピュアJSのみ(=いわゆるバニラJS)で書くと、それでもコード全体は結構な量になります。これをより短く書けるJSフレームワークやライブラリが生まれる訳だなあと思いました。 まとめ:JS完全に理解した……の先へ行ける、モダンJSのまとまった最新情報が得られる本!  と読書メモを並べてみましたが、自分的には案の定というべきか、忘れているところ、理解があやふやなところがあちこちにありました(汗)。よい補完になりました。特に難しいと思ったのはやはりPromise周りでした。改めて理解を深めないと……。  複数の方が関わってコントリビュートしていることもあり、日本語の文章は読みやすいです。このへんは翻訳本に比べると強みですね。また全体的にコード例が豊富かつ簡潔で、(難しいところは難しいのですが)理解しやすいと思います。他の難しそうな本で挫折したという方も本書ならリベンジできるのではと思います。  本書のTwitterハッシュタグ #jsprimer を概観していると多くの人が呟いているのが、「今まで雰囲気でやっていた/理解していたところがよく分かった」というもの。僕も同じような感想を持ちました。変化を続けるJavaScriptについてまとまった、かつ今後もアップデートが期待できる情報源として、学習の傍らや実際の開発の傍らで大いに役立つことでしょう。 JS完全に理解した……の先へ! JS完全に理解した……の先へ行けるリンク集 本と同じ内容のWeb版。最後の『付録:JavaScriptチートシート』が解説ページそれぞれに飛べてとても便利です。 jsprimer.net 本書の続編の位置付けに『JavaScript Promiseの本』も無料公開されています。Promiseだけで一冊本ができるのが凄い……! それぐらいPrromise周りは難しく奥が深いということですね。 azu.github.io コンテンツ自体がオープンソースとして管理された本書のGitHubリポジトリ。 github.com 達人出版会からも出版されています。 tatsu-zine.com はてブ300の大��目を浴びた、なぜ書かれたかの記事。 efcl.info Web版を読んでJSに再入門した方の記事。 pagain.hatenablog.com Web版を読んだQiitaの感想記事。 qiita.com 本書でArrow Functionが分かった方の記事。 www.ry0takahash1.com 本書で学習を始めた方の記事。 自分用メモ JavaScriptの勉強を始めた #jsprimer - Mitsuyuki.Shiiba 500はてブと注目された、Ruby界隈やQiitaでお馴染みの伊藤淳一さんの感想記事。タイトルに埋め込まれたギャグにもっとツッコミを入れて欲しかったそうであります。 『「すでに他の言語のプログラミング経験はあるし、JSもある程度触れるが、ES2015以降の機能は雰囲気でしか理解していない」という人間にはピッタリの一冊でした』という感想に納得です。 blog.jnito.com JS完全に理解した……の先に行ける、モダンなJSが学べる最近の本 本書の作者さんによる、レベル別のJS本のおすすめリスト。JS本も列挙すると色々あるのですが、2010年代後半~の新しい本があまりないんですよね。 JavaScriptのレベル別書籍のまとめ · GitHub 『改訂新版JavaScript本格入門 ~モダンスタイルによる基礎から現場での応用まで』が初版2016年。2019年10月に6版でES2015の情報も強化され、電子版にも更新が入っています。 技術書では安心の山田 祥寛さんの本。評判も良く、言語経験があってJS再入門したい方には今もお勧めです。僕がJS再入門したのもこの本です。リファレンス用に会社の机に1冊置いてあるのですが、今ごろ埃をかぶってるだろうか…… Amazonでベストセラーになっている『確かな力が身につくJavaScript「超」入門』は2019年9月の最新。前述の本よりややランクを落とし、より初心者向け。開発経験のない方、浅い方はまずはここからしっかりやるのも良いと思います。  約束のオライリー本ですと、電子版がないですが『初めてのJavaScript 第3版 ―ES2015以降の最新ウェブ開発』のが2017年1月刊行でぎりぎり最近といえるでしょうか。450ページあります。前述のレベル別リストだとこれも初心者向けの分類となっています。  「サイ本」として有名な『JavaScript 第6版』はさらに鈍器力の高い800ページ越え、こちらは2012年刊行で古めです。この2冊は表紙デザインがやや似ているので注意です。(「初めての~」の表紙はカバさん?) コードサンプルが大量に載ったスタイルの本ですと、『JavaScript コードレシピ集』が2019年1月、『JavaScript逆引きレシピ 第2版』が2018年10月。
