I bought SitePoint book “Simply JavaScript” and Im on chapter 3 right now, but I dont know anything to code. I know just a basics of variables, data types, booleans, functions etc. but thats all theory. I cant build anything than 2 + 2 in variables 
Should I continue reading or I need to go back at the beginning and read again. I know theory, what is what and what something do.
Thanks all.

You can’t just like read the book and to know to code, you need to learn on practical examples.
