# How important is learning JavaScript fundamentals before using frameworks?

I’ve noticed that many beginners jump directly into frameworks like **React, Angular, or Vue** without fully understanding JavaScript fundamentals.

Frameworks make development easier by providing built-in tools for state management, routing, and UI components. However, sometimes developers struggle to debug issues because they don’t fully understand how JavaScript works.

For example, concepts like:

- closures

- promises and async/await

- event loop

- scope and hoisting

Learning JavaScript fundamentals is extremely important before using frameworks. Frameworks are built on top of JavaScript, so understanding core concepts like **functions, asynchronous programming, and object behavior** helps developers write better and more reliable code.

Developers who understand JavaScript deeply usually find it easier to learn new frameworks and debug complex issues.

Would it be better for beginners to focus on **core JavaScript first**?
