ecmascript 6 - Obj-C category/extension Swift in Javascript ES6 -


i'm looking add methods class in javascript es6 without creating subclass of it, in same way categories in objective-c or extensions in swift.

i didn't find information it.

any suggestion?

es6 class syntax syntax sugar on javascript's prototypal inheritance model. add methods class, can add more properties onto prototype.

class {  }  something.prototype.newmethod = function(){  };
