There are several ways you can improve your skills in JavaScript:
Practice, practice, practice: The best way to become proficient in any programming language is to write a lot of code and work on a variety of projects. You can find online resources such as coding challenges or open-source projects to contribute to, or you can come up with your own ideas for projects.
Learn the fundamentals: Make sure you have a solid understanding of the core concepts of JavaScript, such as variables, data types, loops, functions, and objects.
Stay up to date: JavaScript is a constantly evolving language, with new features and best practices being introduced all the time. Make an effort to keep up with the latest developments and best practices in the JavaScript community.
Learn from others: There are many resources available online, such as tutorials, blogs, and forums, where you can learn from experienced developers and ask questions. You can also consider joining a local meetup group or attending a conference to learn from and network with other developers.
Work on real-world projects: In addition to working on smaller coding challenges or practice projects, try to work on real-world projects that solve a specific problem or meet a specific need. This will help you apply your skills in a practical setting and give you experience working on larger, more complex projects.
