I completed javascript course but still i can't understand codes of many projects... like i never seen them before?

Question

Js

Answer 1

Try to remember the basics such as keywords and operators. Leave comments in your codes so that when you look back over them you know what your code means.
You will have to continue to practice what you have learned until it is stored in your long term memory. But you don't have to remember everything. You can use reference.

Answer 2

Probablly cause you havent. Try looking at the methods and keywords used and look them up if you don't know about it. Or think of how completing the js course means you now know the basics. Thats it. There's a lot more to learn and this is happily just the beggining

Answer 3

Try to write your own code similar to these and look up documentation.

Answer 4

But I never seen things like these in js... where do i learn from?...
