JavaScript Callable Object using proxy

index.js

'use strict'

class Callable extends Function {
  constructor() {
    super()    
    return new Proxy(this, {
      apply: (target, thisArg, args) => target._call(...args)
    })
  }
  
  _call(...args) {
    console.log(this, args)
  }
}

It works! Very clean solution. Thank you.

No prob, there are other approaches to callable objects, have a look at the other gists, or this article.

Thanks for the link, it's a good read.

you could also reuse the object itself!

class Callable extends Function {
  constructor() {
    super()    
    return new Proxy(this, this)
  }
  
  apply(...args) {
    console.log(this, args)
  }
}
