React is fun itself. No JSX,Babel

It’s really fun to know how to use React without JSX, Babel and some bunch of stuff. It's helped me understand the main principle of React library, thanks Brian Holt form Netflix and Frontend Masters course. If you use React, how do you explain the difference between createClass and createElement? - yes, it’old stuff, now all use ES6 class syntax, but it’s pretty fun to clarify the core principle of react.  Sure I don’t use it in production just for understanding the key principles

When JavaScript Promises

Through this article, we are going to see what Promises are in JavaScript and how we can use them.

Introduction

Promises are now widely used in JavaScript, but they can stay a little confused. Promises were introduced by ECMAScript 6. They intend to provide a way to deal with the completion of asynchronous tasks. They are an alternative to callbacks for delivering the results of an asynchronous computation.

Just for a simple refresh, a callback function, also known as a higher-order function, is a function that is passed to another function as a parameter. The function is called inside this other function.

One of the biggest problems of callbacks is the chaining of different asynchronous activities, because we end up with a growing stack of callback functions (callback hell). Promises aim to provide a solution to this problem and an alternative for executing, composing and managing asynchronous operations.

How it works

A Promise is an object that can be returned synchronously from an asynchronous operation and it can have one of the following states:

Pending: we don't know the outcome because the operation that will produce the result hasn't completed yet.

Fulfilled: the operation has completed and we have a value

Rejected: the operation failed

A Promise is settled if it’s not pending.

Resolve, Reject

The Promise constructor takes one argument: a callback function with two parameters, resolve and reject. It is our responsibility to call resolve and reject, and eventually to pass values to them.

Let's make a very basic example with what we know:

const p => time = new Promise((resolve, reject) => { if (time < 1) { reject('Failure'); return; } setTimeout(resolve('Success'), time); });

In this example, we just create a Promise that will return 'Success' after a given time or will fail if the given time is smaller than 1. Here, we placed a return after the reject to terminate the control flow and to prevent the execution of extra code, but it is not strictly needed.

Then / Catch

How can we use the Promise that we created? We can do it with the then method. This method takes two arguments, resolved and rejected. This last one is optional and is called when the Promise is rejected. We could do it like so:

p(500).then((resolved) => { console.log(resolved); }, (rejected) => { console.log(rejected); });

We can also use the catch method to handle errors.

p(500).then((resolved) => { console.log(resolved); }).catch((error) => { console.log(error); });

In case of error, we can also use throw. We can use it any time we are inside a Promise callback, but if we are in any other asynchronous callback, we have to use reject because otherwise catch won't be triggered and we will be left with an unresolved Promise and an uncaught exception.

// Uncaught exception const p = new Promise((resolve) => { setTimeout(() => { throw 'Error'; }, 500); }); p.then((res) => { }).catch((error) => { console.log(error); // won't happen }); // Caught exception const p = new Promise((resolve) => { setTimeout(() => { resolve('Ok'); }, 500); }); p.then((res) => { throw 'error'; }).catch((error) => { console.log(error); });

Chaining

The then method returns a Promise which allows for method chaining.

p(500).then((val) => { console.log(val); return val; }).then((val) => { val = val + ' ' + 'foo'; console.log(val); }).catch((error) => { console.log(error); });

Promise.all()

The Promise.all method returns a single Promise that resolves when all of the Promises passed in the argument have resolved. So, this method takes an array of Promises and fires one callback once they are all resolved. It can be used to aggregate the results of multiple Promises.

const p = time => new Promise((resolve, reject) => { if (time < 1) { reject('Failure'); return; } setTimeout(resolve('Success'), time); }); const p2 = new Promise((resolve, reject) => { setTimeout(resolve('Another promise'), 1000); }); p(500).then((val) => { console.log(val); return val; }).then((val) => { val = val + ' ' + 'foo'; console.log(val); return Promise.all([p2, val]); }).then(([p2, val]) => { console.log(val + ' ' + p2); }).catch((error) => { console.log(error); });

Conclusion

In this article, we saw what Promises are and how we can use them. We saw that Promises are an alternative to callbacks for delivering the results of an asynchronous computation.

JavaScript: Let and Const Explained

JavaScript: Let and Const Explained

ECMAScript 6 (ES6), also colloquially known as JavaScript 6, is the latest standard of JavaScript as introduced in 2015. ES6 came with many important features, such as arrow functions and spread and rest operations, which we will be discussing as we go. Today, we are discussing the new declaration statements let and const and why we require them.

Photoshopの問題

エルヴァートでは基本的に画像編集にPhotoshopを用いています。エルヴァートマップがPhotoshopでのマクロを用いた編集だからなのですが。以前は、単に画像をアップロードするだけでも、Photoshopを起動してマクロ（スクリプト）を呼び出していました。アップロード本体はJavaによる自作ツールで、エルヴァートマップのアップロードも通常画像のアップロードも、子プロセスを起動して呼び出しています。ちなみにEmEditorからのアップロードも子プロセスで同じツールを呼び出しています。

ただ、Photoshopは何しろ「重い」のです。起動も非常に時間がかかるし、なんてことない画像でも非常に多くのメモリを消費する。スクロールするだけでも重い。編集が伴うならともかく、単に画像（自作ツールによる系図画像を含む）をアップロードするためだけに起動するのは、やはり馬鹿らしい。

ということで、しばらく前にエクスプローラの右クリックから直接Javaのアップロードツールを呼び出すようにしました（「送る」メニュー）。

また、作家様に描いていただいた画像は、Webページ埋め込み用の横300のサムネールを作成して同時にアップロードしており、これも以前はPhotoshopマクロでやっていました。やることが決まっているのだし、Photoshopは重い…ということでJavaでツール（サムネール作成・保存＆画像2つアップロード） を作り、「送る」メニューで呼び出すように。

さらにもう一つ。系図画像に使用する96×128のサムネールの作成も、以前はPhotoshopでした。画像の顔部分を3:4で切り抜き、96x128に縮小して別名保存です。これもJavaでツールを作り、「送る」メニューに登録しました。これらにより、Photoshopを起動しないといけない場面はかなり減らすことができました。

なお、縮小時はImage.getScaledInstance()を用いています。パラメータは Image.SCALE_SMOOTH。処理は遅いですが一番質の良い画像が得られますし、私が扱う画像程度なら誤差の範囲内です。

Photoshopは上記のようにその重さが問題ですが、もう一点とても大きな問題があります。一度でも起動すると、Creative Cloudからの更新に失敗することです（「ファイルが使用中で更新できませんでした 」 になる）。しかも現在のインストールセットを削除した上で更新→失敗なので、起動すらできなくなります。CCを使い始め時から変わっていません。

こうなるとPC自体を再起動し、再度Creative Cloudを起動して更新する必要があります。普段使いのマシンはともかく、リモートデスクトップで接続しているエルヴァートマップ編集用PCは結構面倒です。動作の軽量さやセキュリティに関しては、 Adobeは正直ひどいものです。

とはいえ、代替ツールは正直ありません。自作可能な範囲はごく一部。また一般的な編集ならフリーのツールをはじめ、Affinity Photoという有力な選択肢が出ています。ただ、Affinity Photoはスクリプト機能がないことがエルヴァートマップにとって致命的です（すべて手作業でやるのはもう無理です）。ExtendScript…今だとECMAScript6ですが、対応してくれればおそらくあっさり乗り換えるでしょう。それが出てこないため、Photoshopを使い続けるしかありません。

ECMAScript6 or ECMAScript 2015, which is designed by Brendan Eich, Ecma International, is a general- purpose client-side scripting language specification. It governs JavaScript (along with JScript and ActionScript).

prototype, __proto__ and classes with JS

Those aforementioned three words are relative to JavaScript and could sound very weird. Let's try to understand them!

JavaScript’s object system is based on prototypes, not classes. But what is the difference?

A class is like a blueprint. It is  a description of the object to be created. Classes inherit from classes and create subclass relationships.

A prototype is a working object instance. Objects inherit directly from other objects.

Every JavaScript object has a prototype. The prototype is also an object. All JavaScript objects inherit their properties and methods from their prototype. Objects created using an object literal, or with new Object(), inherit from a prototype called Object.prototype. The Object.prototype is on the top of the prototype chain.

function talk() { console.log(this.sound); } let animal() { talk; } let cat() { sound: "Dog" } let cat() { sound: "Maouw" } Object.setPrototypeOf(dog, animal); Object.setPrototypeOf(cat, animal); dog.talk; //will output "Woof" cat.talk; //will output "Maouw"

If we want to add a property or a method to the prototype, we can do it like so:

Animal.prototype.name = "My pet"; Animal.prototype.beNice = function() { console.log("I am nice"); };

We can also use the new operator which will call a constructor function. A constructor could be any function. Basically, when a constructor function is called, the following things happen:

A new object is created

The constructor property of the object is set

The object is set to delegate to the prototype

The prototype is called in the context of the new object

So, with a constructor function, we can use the new keyword to create new objects from the same prototype:

function Animal(sound) { this.sound = sound; this.makeSound = function() { console.log(this.sound); } } var dog = new Animal("Woof"); var cat = new Animal("Maouw"); dog.makeSound(); //will output "Woof" cat.makeSound(); //will output "Maouw"

Adding a new property to an existing object can be done like that:

dog.color = "Brown";

The property will be added to dog, not to cat and not to any other Animal objects.

Adding a new method to an existing object can be done this way:

cat.playWithMouse = function () { return "I am playing with a mouse!"; };

The method will only be added to cat.

Now, maybe you saw something like __proto__ and asked what it is.

__proto__ is the actual object that is used in the lookup chain to resolve methods. It is a property that all objects have. This is the property which is used by the JavaScript engine for inheritance. According to ECMA specifications it is supposed to be an internal property, however most vendors allow it to be accessed and modified. The use of __proto__ is controversial, and has been discouraged. It was never originally included in the ECMA specifications, but modern browsers decided to implement it anyway.

prototype is a property belonging only to functions. It is used to build __proto__ when the function happens to be used as a constructor with the new keyword.

So, where are the classes? In essence, a JavaScript class is just a Function object that serves as a constructor plus an attached prototype object Empty also referred as this. Classes in ES6 don't add any functionality to what we already have in the language, they are just a simpler syntax for building the same objects as we had before. The class syntax is not introducing a new object-oriented inheritance model to JavaScript. JavaScript classes provide a much simpler and clearer syntax to create objects and deal with inheritance.

class Animal { constructor(sound) { this.sound = sound; } talk() { console.log(this.sound); } }
