JavaScript Developer Roadmap: Step by step guide to learn JavaScript (original) (raw)

A JavaScript developer needs to have a solid grasp of core JavaScript concepts to be successful because those will be the only common concepts that any framework or library they might depend on will use.

These 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 also 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.

Candidates looking to prepare for JavaScript developer interview questions should include the above-mentioned topics in their study program. For that, many developers schedule their studies at their own pace through extensive documentation, online training, and roadmaps like this one to build a solid foundational knowledge base.
