MDN’s new design is in Beta! A sneak peek:

The static Reflect.apply() method calls a target function with arguments as specified.


Reflect.apply(target, thisArgument, argumentsList)


The target function to call.
The value of this provided for the call to target.
An array-like object specifying the arguments with which target should be called.

Return value

The result of calling the given target function with the specified this value and arguments.


A TypeError, if the target is not callable.


In ES5, you typically use the Function.prototype.apply() method to call a function with a given this value and arguments provided as an array (or an array-like object)., undefined, [1.75]);

With Reflect.apply this becomes less verbose and easier to understand.


Using Reflect.apply()

Reflect.apply(Math.floor, undefined, [1.75]); 
// 1;

Reflect.apply(String.fromCharCode, undefined, [104, 101, 108, 108, 111]);
// "hello"

Reflect.apply(RegExp.prototype.exec, /ab/, ['confabulation']).index;
// 4

Reflect.apply(''.charAt, 'ponies', [3]);
// "i"
