What does a freelance JavaScript developer do?

A freelance JavaScript developer is a self-employed professional who specializes in using the JavaScript programming language to build websites, web applications, or add interactive features to existing sites. They typically work with clients on a project-by-project basis, handling tasks such as front-end development, back-end scripting (often with Node.js), debugging, and integrating APIs. Freelance JavaScript developers need strong coding skills, good communication, and the ability to manage their own schedules and deliverables.
