How does prototype extend on typescript?

Question

i extended function prototype but typescript doesn\'t recognize it.

Function.prototype.proc = function() {
  var args, target, v;
  var __slice = [].slice;
          


        

Answer 1

Like this:

declare global {
    interface Function {
        proc() : any;
    }
}

Without 'declare global' it doesn't work.

That's how module augmentation works in recent TypeScript versions. Check out the documentation and scroll down to the Module augmentation section.
