I took the 30-Days Javascript Challenge, which helped me build a deep understanding of Javascript. In this challenge, we have to create 30 projects related to Javascript that will help you gain a better understanding of Javascript. The challenge is open to beginners and experienced developers alike. You don't need to have any prior JavaScript experience to participate, but it will be helpful if you have some basic HTML and CSS knowledge. Each day of the challenge, you'll learn a new JavaScript concept and then apply it to a project. The projects range from simple to complex, so you'll be challenged but never overwhelmed. I really enjoyed the challenge because it helped me learn JavaScript in a practical way. I was able to see how the concepts I was learning could be applied to real-world projects.
One of my seniors advised me that if you want to learn Javascript with clarity, you must develop a good project that aids in your understanding of the language. They recommend Wes Brothers' 30-day Javascript challenge. They also share their story about how this challenge helped him get a good command of JavaScript. I give you a website link where you put your email address and where you get all the project details in your email, and then you start learning and creating projects.
