Get rid of `this` thing

thisless.js

"use strict"

// Attempt to shoehorn Lua's (or Python's) "first parameter is `this`" model
// into JS's object model.  Makes us not have to worry about `this` at all.

Function.prototype.applyW = function (args) {
  return this.apply(null, args)
}

function wrap(fn) {
  return function (/*...*/) {
    "use strict"
    return this == null?  fn.apply(null, arguments)
         : /*else*/       fn.bind(null, this).apply(null, arguments)
  }
}

//-- Testing area ---------------------------------------------------
var add = wrap(function (x, y) { return x + y })
Number.prototype.add = add

console.log(add(1,2))          // --> 3
console.log(add.call(1,2))     // --> 3
console.log(add.bind(1)(2))    // --> 3
console.log(add.applyW([1,2])) // --> 3
console.log((1).add(2))        // --> 3
