You: “May I use a framework such as React or Vue for this prompt?”

Interviewer: “No, please complete the prompt in vanilla JavaScript.”

You: Ahh, vanilla JavaScript… it makes even seasoned web developers break out into a cold sweat. But, with a little practice in the fundamentals, you might learn that vanilla JavaScript (JS) can be your friend! :)

This article serves as an introduction to a multi-part tutorial on vanilla JavaScript. The tutorial begins in the next article.

What is vanilla JS, and why should I spend any time on it?

“Vanilla JS” is a casual nickname the programming language JavaScript in its pure form, without the benefit of any added frameworks or libraries (such as React or Vue, as mentioned above). Such frameworks and libraries are not only helpful in a professional setting, they are imperative! However, most veteran programmers would recommend that beginning programmers not start with such tools, as they can sometimes impair your underlying conceptual understanding of web development. Starting with the no-frills version of JS will lead to more concrete understanding of how the code interacts with the browser, which is a core component of web development.
