param spread helper

gistfile1.js

// thanks to @raganwald
function spread(fn) {
    return Function.apply.bind( fn, null );
}

function foo(x,y,z) {
    console.log(x,y,z);
}

function bar(fn) {
    fn( [1,2,3] );
}

bar( spread( foo ) ); // 1 2 3

gistfile2.js

// In ES6, we have param destructuring to help

function foo( [x,y,z] ) {
    console.log(x,y,z);
}

function bar(fn) {
    fn( [1,2,3] );
}

bar( foo ); // 1 2 3
