He estado practicando call, apply, bind polyfills y de repente me di cuenta de que no es realmente un polyfill si uso operadores de propagación/descanso, no puedo entender cómo pasar argumentos en call sin él, ¿alguna idea amigos?

 //my attempt to write call polyfil without spread operator //but it doesn't work Function.prototype.call = function () { const obj = arguments[0]; obj.fn = this; const args = Array(arguments).slice(1).reverse(); while (args.length) { obj.fn.arguments.push(args.pop()); } //obj.fn.arguments = Array(arguments).slice(1); obj.fn(); }; // that one works, but it uses spread operator Function.prototype.call = function (obj, ...args) { obj.fn = this; obj.fn(...args); }; Function.prototype.apply = function (obj, args) { obj.fn = this; obj.fn(...args); }; Function.prototype.myBind = function (obj, ...args) { const fn = this; return function (...newArgs) { const allArgs = [...args, ...newArgs]; fn.call(obj, ...allArgs); //fn.apply(obj, allArgs); }; }; let obj = { name: "Jack", }; let myFunc = function (id, city) { console.log(`${this.name}, ${id}, ${city}`); }; let newFunc = myFunc.myBind(obj, "a_random_id"); newFunc("New York"); // Jack, a_random_id, New York
