Hello Guys! Welcome to Coding Torque. In this blog, I’m going to explain to you how to make a QR Code Generator using HTML, CSS, and JavaScript. This will be a step-by-step guide. Let’s get started 🚀.
Before we start, here are some JavaScript Games you might like to create:
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. Whack a Mole Game using JavaScript
I would recommend you don’t just copy and paste the code, just look at the code and type by understanding it.
