However, certain fundamental concepts frequently appear in interviews, serving as foundational knowledge for JavaScript developers. Questions about data types, variable scope, and function invocation are ubiquitous, assessing candidates’ understanding of JavaScript’s core principles. Additionally, proficiency in manipulating arrays and objects, as well as knowledge of control flow statements, is often scrutinized. Questions related to asynchronous programming, including promises and callbacks, are essential for roles involving web development or backend JavaScript frameworks.
