I'm currently learning full-stack development with JavaScript and want to prepare for technical interviews by studying data structures and algorithms. Is it fine to learn and practice DSA in JavaScript, or would switching to Java give me an advantage? I'm also unsure whether I should choose a different language for DSA and backend development as a college student.

The language usually doesn’t matter much—DSA concepts are largely language-agnostic. Use JavaScript if you already know it well, since being comfortable with the language is more important than choosing a specific one. You can implement stacks, queues, and similar structures yourself when needed; built-in features aren’t a reason by themselves to switch.
You can learn DSA in either JavaScript or Java. For interviews, the best choice is usually the language you’re most comfortable writing quickly and accurately. If a particular company requires or strongly prefers a language, practice in that language for the interview. As a student, it’s also reasonable to keep JavaScript for your full-stack work and learn Java separately only if your target backend roles or interview process call for it.
I was wondering because I read that JavaScript doesn’t have as many built-in functions for structures like stacks and queues.
