Why Javascript fundamentals are stopping you!!!

When i started the development journey, hoping from one video to another in order to get the job, I prepared 2-3 MERN/MEAN stack projects. I got the job and after that once again when I wanted to switch and prepare for high package job I got stuck in tutorial hell for months.

React tutorials, Next.js courses, TypeScript bootcamps - nothing clicked.

2 weeks of pure fundamentals.

The result?
I haven't touched a tutorial in 2 months.
Problems I used to Google for hours?
Solved in minutes.

  • Stop chasing frameworks.
  • Master the language first.

Most developers learn React before understanding JavaScript. It's like learning to drive before understanding how cars work.

๐Ÿ”น Closures - Why your variables sometimes "disappear"
๐Ÿ”น Event Loop - Why your app freezes (and how to fix it)
๐Ÿ”น Prototypes - How JavaScript really works under the hood
๐Ÿ”น Hoisting - Why your code breaks in production but works locally
๐Ÿ”น Async/Await - Why your API calls fail silently
๐Ÿ”น Scope Chain - Why your functions can't find variables
๐Ÿ”น Reference vs Value - Why your state updates don't work

  • That infinite re-render? JavaScript closure issue.
  • That undefined error? JavaScript hoisting problem.
  • That state not updating? JavaScript reference issue.

The biggest mistake I made:
I thought fundamentals were boring. They're not.

They're the difference between copying code and understanding code.

Bottom line: You can't build advanced React apps on shaky JavaScript foundations.

Fix the foundation first. Everything else becomes easier.
