Extend a String class in ES6

Question

I can write the following in ES5:

String.prototype.something=function(){
  return this.split(\' \').join(\'\');
};

How do I do the same thi

In ES6 you can also do it with Object.assign() like this:

Object.assign(String.prototype, {
    something() {
        return this.split(' ').join();
    }
});

You can find more info to the method here.

Or you could use defineProperty (I think that would be better here):

Object.defineProperty(String.prototype, 'something', {
    value() {
        return this.split(' ').join();
    }
});

See the docs here.

See my comment to see when to use defineProperty vs Object.assign().
