Introduction
In this lab, we will be exploring a JavaScript function that helps us find the common keys between two objects. We will use the Object.keys() method to get the keys of the first object, and then check if the second object has a key that matches using Object.prototype.hasOwnProperty(). Finally, we will use Array.prototype.filter() to filter out the keys that are not common to both objects. By the end of this lab, you will have a solid understanding of how to efficiently find common keys between two objects in JavaScript.
