I have a very big ques as a beginner

The best way to learn is via a course: a human teacher can rephrase or rework a lesson, and also mark your homework to ensure you are learning the right things, and correct you when you go wrong.

The next best is a book - there are many, start with Addison Wesley, or Wrox - just avoid anything with multiple exclamation marks, "for dummies", or "in xx days" in the title. Read it from beginning to end, doing all the exercises.

The first worst is to learn for yourself: basically guessing and trying things until it works. THat a very bad way to do it as you can't use stuff you don't know about - and you have no way to find out what you don't know!

The absolute worst way to learn is via YouTube tutorials: they are generally produced by people who have no idea how to teach, how to make a video, and in most case no idea how to code either. There are probably good ones out there, but the are well and truly hidden in a huge, steaming pile of junk. Remember that they are produced to make money from "likes and subscribes" ratehr than to actually help you...
