What does a JavaScript developer do?

A JavaScript Developer is responsible for designing, developing, and maintaining web applications using the JavaScript programming language. They typically work on both the front-end (user interface) and sometimes the back-end (server-side) of web projects, creating interactive features, optimizing performance, and ensuring cross-browser compatibility. Their role often involves collaborating with designers and other developers to deliver a seamless user experience.

What are the key skills and qualifications needed to thrive as a JavaScript developer, and why are they important?

What are some common challenges faced by JavaScript developers when working on large-scale applications?
