In simple terms, you can use your favorite JavaScript frameworks to send HTTP requests, create dynamic user experiences, and generate interactive content. A critical requirement for a developer who is expected to complete the work with minimal supervision or the ability to structure their code in a maintainable manner.

Often, when conducting a technical evaluation, the programmer is asked to write a code snippet to evaluate their technical quality and culture.

Based on your requirements, you can decide if you need a developer with specific skills or a broader skill set, and you can recruit accordingly. In short, JavaScript is an object-oriented programming language that brings web pages and applications to life. Basically, web browsers are the primary users of JavaScript because they use it to generate an interactive and engaging interface for users.
