es6-spread

Compiles JavaScript written using ES6 spread syntax to use the equivalent ES5 code. For example, this:

function f(x, y, z) { }
var args = [0, 1, 2];
f(...args);

compiles to this:

function f(x, y, z) { }
var args = [0, 1, 2];
f.apply(null, args);

This project is part of esnext, a project to compile the syntax of the next version of JavaScript to today's JavaScript environments.

For more information about the proposed syntax, see the wiki page on spread.
