<span class="alias">Alias: <b>restArgs</b></span>
<br />
Similar to ES6's <a href="https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/rest_parameters">rest param</a>,
<code>restParam</code> collects arguments passed to a function from
a given <code>index</code> as an array.

<pre>
function multiply(multiplier, ...theArgs) {
return theArgs.map(function (element) {
return multiplier * element;
});

It'd probably be more helpful to show how a restParam function translates into ES6.


var arr = multiply(2, 1, 2, 3);
console.log(arr); // [2, 4, 6]
