+### bind
+
+Creates a function that invokes `fn` with a given context, optionally adding any additional supplied parameters to the beginning of the arguments.
+
+Return a `function` that uses `Function.apply()` to apply the given `context` to `fn`.
+Use `Array.concat()` to prepend any additional supplied parameters to the arguments.
+
+```js
+const bind = (fn, context, ...args) =>
+  function() {
+    return fn.apply(context, args.concat(...arguments));
+  };
+```
+
+```js
+function greet(greeting, punctuation) {
+  return greeting + ' ' + this.user + punctuation;
+}
+const freddy = { 'user': 'fred' };
+const freddyBound = bind(greet, freddy);
+console.log(freddyBound('hi','!')); // 'hi fred!'
+```
