// Assign first and second to the first two values in the array.
var nums = [1, 2, 3];

var firstES5 = nums[0];
var secondES5 = nums[1];

var [firstES6, secondES6] = nums;

// Assign the foo and bar properties from the object.
var object = {foo: 1, bar: 2};

// ES5
var foo = object.foo;
var bar = object.bar;

// ES6: This pattern matches the variable name to the object property
var {foo, bar} = object;
