It takes upto 5 to 7 months to learn javascript normallySo, I've self-taught myself HTML, CSS and PHP for many months as I just wanted to expand my skill toolbox. However, JS is another type of programming that I am quite interested in and it links heavily with the project I am working on.
How hard is it to self-teach this compared to HTML, CSS and PHP?
But if you good in learning skills you can learn within 4 months
It's upto you how much time you give to learn javascript.
