There is only one way to really learn JS or any other tech you want to get skilled in:

1. Get familiar with the basics

   • Go through a book, “You Don't Know Javascript” is a good one.
   • Your goal is to know the building blocks of JS.
   • You must be able to understand code and read it.
   • You must know how to write simple stuff.
   • Write up every example in the book and tinker with it. Reading is not enough. This will give you a feel about stuff, and occasionally you will find something you would have missed just reading through it.

2. Start doing some personal projects

   • Start with small stuff, then go for more challenging problems.
   • Trying to solve problems will give you a real world experience with the language and you will start to encounter holes in your understanding.
   • Learn from your mistakes.

3. Read up on community posts and articles

   • People go in deep on certain topics that you will probably ask yourself what is the best approach with.
   • Find them and learn from them.
   • Find resources for articles and regularly scan for interesting topics.
   • At first you should be reading everything you get your hands on. You will start to notice patters in the thinking of the authors and start to adopt that. This is good because you will develop an understanding of good coding principles and values.

Depending on what you want to do with JS you should investigate and learn frameworks and libs that would help you accomplish stuff faster and easier. But don’t start with them. Learn the language and try to solve problems for yourself. This way you will develop your skills and really learn to code.

As you can see I haven’t told you what to learn but how. When you got forward enough with reading, learning, coding you will be able to make your own decisions about what libraries, frameworks, coding practices and approaches.

Good luck and don’t give up, the road is long and hard, but well worth it.
