Hello coders! Are you ready to test your coding skills and put your knowledge of HTML, CSS, and JavaScript to the ultimate test? If so, you've come to the right place! In this blog, we will be walking you through the steps to create your very own Hangman game from scratch. Not only is this game a fun and engaging way to pass the time, but it's also a great way to enhance your portfolio and showcase your abilities as an intermediate-level JavaScript developer. So grab your coding hat and let's get started!

Before we start, here are some more JavaScript projects for you to practice:
1. Snake Game using JavaScript
2. 2D Bouncing Ball Game using JavaScript
3. Rock Paper Scissor Game using JavaScript
4. Tic Tac Toe Game using JavaScript
5. QR Code Generator using JavaScript
I would recommend you don't just copy and paste the code, just look at the code and type by understanding it.
