Is learning Vanilla JavaScript still important?

"With so many frameworks like React, Vue, and Angular being popular, many beginners don't learn plain JavaScript first. Do you think it's still important to know Vanilla JS, or is it okay to start with a framework? Always, always, ALWAYS learn the basics. Frameworks are great until they introduce a bug which you can't catch unless you understand the fundamentals."

"Always, always, ALWAYS learn the basics. Frameworks are great until they introduce a bug which you can't catch unless you understand the fundamentals."

Knowing plain JavaScript fundamentals is essential before adopting frameworks. Frameworks abstract many browser behaviors and can hide implementation details that cause bugs. Core concepts to master include DOM manipulation, event handling, scope and closures, prototypes, the event loop and asynchronous patterns, and memory management. A solid grasp of fundamentals enables more effective debugging, performance tuning, and informed framework choice. Learning Vanilla JS first builds transferable skills that make frameworks easier to learn and prevents reliance on abstractions that can produce brittle, hard-to-diagnose code.
