In EcmaScript 2015 (ES6) the expression (x) => x * 2 means to create an anonymous function with one parameter x that will return x * 2. For example:

(x) => x * 2
// is equivalent to:
function(x) { return x * 2; }

A modified example from [documentation by Mozilla Developer Network][1] page demonstrates how they are useful:

var a = [

"Hydrogen",

	function fieldSorterOptimized(fields) {
	var dir = [], i, l = fields.length;
	fields = fields.map(function(o, i) {
	if (o[0] === "-") {
	dir[i] = -1;
	o = o.substring(1);
	} else {
	dir[i] = 1;
	}
	return o;
