In the last 10 days, you will work on final projects and practice your JS skills. You can choose a project based on your interest and apply the concepts and techniques learned in the previous 90 days. Some project ideas could be a weather app, a quiz game, a to-do list, or a social media clone. You can also participate in coding challenges and competitions, practice coding interview questions, or contribute to open-source JS projects on GitHub.

Learning JS can be an exciting and rewarding journey, and committing to 100 days of JS can help you become proficient in the language. With a structured plan, you can learn the basics of JS, DOM manipulation, functions and scope, arrays and objects, ES6 features, asynchronous programming and Promises, AJAX and APIs, React basics, React hooks and Redux, and work on final projects and practice.
