How Can I Efficiently Get an Array of Object Keys in JavaScript?

Retrieving Array of Object Keys

Accessing the keys of a JavaScript object as an array can be a common task. While using a loop to iterate through the object's properties is one approach, there may be a more efficient and concise way to achieve this.

For those seeking a less verbose method, Object.keys offers a straightforward solution. This built-in function takes an object as an argument and returns an array containing its keys.

Consider the following example:

var foo = {
  'alpha': 'puffin',
  'beta': 'beagle'
};

var keys = Object.keys(foo);
console.log(keys); // ['alpha', 'beta'] // or some other order

As you can see, this method provides a much cleaner and more concise way to retrieve the keys of an object without the need for loops or manual array population.
