What language should I learn if I want to get into programming? And where could I learn?
You may have heard that it doesn't really matter at all. Yes, it really doesn't matter how you start. Some languages are fancier than others meaning you may have to worry about certain things that you may not in others (data types, memory management, clousures, etc...), but the general logic building part of them is shared between them all. However, different languages may do things differently, so here's a taste of some of the popular ones and what they do differently.
For where, just google something or use a youtube tutorial, as the internet is full of free resources to learn. There's also the mdn web tutorials for getting into web dev which is my sort of specialty and i am a bit biased towards recommending it, but in reality you should choose what area of programming is actually interesting.
