Main Concepts in React

Learning JavaScript doesn’t have to be intimidating.

If you’re just starting out,

Here’s how to simplify your approach:

Avoid:
🚫 Trying to learn every framework (React, Angular, Vue) before mastering plain JS.
🚫 Jumping into async, closures, or OOP too early.
🚫 Watching endless tutorials without building anything.
🚫 Thinking JavaScript is only for the browser.

Instead:
✅ Focus on the core concepts: variables, functions, loops, arrays, objects.
✅ Build small projects like a calculator, to-do list, or quiz app using only JavaScript.
✅ Learn DOM manipulation—how JS connects with HTML/CSS.
✅ Understand event handling and how user interactions work.
✅ Practice debugging with DevTools and log your learning through projects.
