Some thoughts on the use of bind method

[Nirvana-Jie]

Is your feature request related to a problem? Please describe.

When I was looking at the code, I found a very magical thing. When we use the encapsulated bind method, we will find that when we extend the function, all the methods we mount are named wrap, which is unsemantic.

And every time we use the bind method, we will create an array,I think this will be a big waste of resources

module.exports = function bind(fn, thisArg) {
  return function wrap() {
    var args = new Array(arguments.length);
    for (var i = 0; i < args.length; i++) {
      args[i] = arguments[i];
    }
    return fn.apply(thisArg, args);
  };
};

function extend(a, b, thisArg) {
  forEach(b, function assignValue(val, key) {
    if (thisArg && typeof val === 'function') {
      a[key] = bind(val, thisArg);
    } else {
      a[key] = val;
    }
  });
  return a;
}
