Top JavaScript Tricks and Tips

In this article, we are going to look at some helpful JavaScript tricks.

When you write your code, you may feel that there was a better way of doing this. So let me show you some interesting tricks you might use in your code and make your code shorter and more straightforward.

We are going to understand the fundamentals of these tricks and their use case. Let me start with a simple one that you probably know. Or not.
