JavaScript

One needs to have a knowledge of JavaScript concepts those will be the only common concepts that any framework or library they might depend on. The core concepts include functions, operators, and data structures. And they should include experience with at least one JavaScript framework or core library, such as React for building interactive websites or NextJS for backends. If their focus is back-end development, concepts such as API design and integration, data modeling, server-side rendering, and database querying are a must, as these will be part of the developer's daily tasks. Front-end developers should learn about web standards, the DOM API, web components (or lightning web components if you're working with the Salesforce ecosystem), and have some basic understanding of UX.

While JavaScript is a powerful and versatile language that forms the backbone of modern web development, it is still advised to keep upgrading your resume with more and more modern tools, languages, and relevant projects. Individuals having relevant degrees in programming, like BTech and BCA, should not just settle on one programming language in the rising competition for even entry-level jobs. Pairing up your JavaScript skills with related technologies, frameworks, and practical project experience will significantly improve your chances of landing a job. A broader skill set is always preferred by some of the top recruiters for JavaScript and other programming languages jobs.
