How Can I Efficiently Convert a JavaScript Object to an Array?

Converting a JS Object to an Array: An Efficient Approach with jQuery

While iterating over a JavaScript object using jQuery's $.each method can convert it to an array, there are more efficient ways to achieve this conversion.

For a functional approach:

var obj = {1: 11, 2: 22};
var arr = Object.keys(obj).map(function (key) { return obj[key]; });

This will result in:

[11, 22]

With an ES6 arrow function:

Object.keys(obj).map(key => obj[key])

Or with ES7's Object.values method:

var arr = Object.values(obj);

For a simpler approach using Underscore/Lo-Dash:

var arr = _.values(obj)
