Hey and welcome to the forums!
It really depends on what you’re looking for exactly and what you’re struggling with. W3Schools is always a great resource to have to hand when doing programming, they have a page on pretty much everything for most languages. Also just googling specific problems of course helps.
If you’re struggling with the concept of a loop, it might be worth going back over the section again or you might consider the Codecademy’s Basics of Programming course. This takes you through learning how to program without specifying a language, and lets you grapple with just the concepts as opposed to learning syntax also. Sometimes I also find that when I’m struggling with a particular concept, just breaking it down on a piece of paper as to what exactly it is doing can help me understand it.
Of course if you’re having a specific coding problem, you are always welcome to ask here. Maybe it’s not so much a concept problem as you’re just struggling on particular syntax quirks. If you have any specific examples of what you don’t understand I would be happy to try give a different explanation!
