Cave Man and `JSON.stringify`

The JSON.stringify() method converts a JavaScript value to a JSON string, optionally replacing values if a replacer function is specified, or optionally including only the specified properties if a replacer array is specified.1

Using javascript, I used to do cave-man debug using console.log(). In some cases, I console.log() to get the data returned from ajax call (using jQuery). E.g:

$.post('/my-url',my-post-data) .done(function(data){ console.log('done'); });

Above code is useful to indicate that our script is succesfully executing done callback. But I also want to log what's inside data. Unfortunately, if I concat data directly:

console.log('done'+data);

It will return: done[object Object] which is not what I want.

Well, that makes sense since the data is an object. So, here is where JSON.stringify() come to help. Just wrap the data:

console.log('done:'+JSON.stringify(data));

And it will return:

done:{"sample1":"sample-data-1","sample2":"sample-data2"}

That is one of my experience using JSON.stringify(). See you to the next post :D
