javascript - Extend a String class in es6 -

i can write following in es5:

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

how do same thing in es6 using new features ?

ps : know valid es6. wan't know whether there's other way of implementing such functions in es6 shorter ? above function example.

in es6 can object.assign() this:

object.assign(string.prototype, {     something() {         return this.split(' ').join();     } });

you can find more info method here.

or use defineproperty (i think better here):

object.defineproperty(string.prototype, 'something', {     value() {         return this.split(' ').join();     } });

see docs here.

see comment see when use defineproperty vs object.assign().
