Javascript Object keys: How to Get Object Keys in JavaScript

Javascript Object keys() is a built-in method that returns an array of the given object’s property names in the same order as we get with a standard loop. The Object keys() method is used to return the array whose elements are strings corresponding to the enumerable properties found directly upon the object.

How to use Object.keys() method

First, install  Node.js if you have not because we are using  Node.js and  NPM to run the javascript examples. It is not compulsory, though, if you want to use an online editor or browser.
