Learning how to code

Hi i just want to know how you would learn how to code or create codes on your own after learning a decent amount of coding, i have seen a few tutorials but they don’t really explain coding as clear as i would like them to, so are they any coding tutorials that teach you everything from scratch? (Unity Related not general coding such as applications etc)

The type of tutorials i’m intrested in are…
Videos and not reading as it can become confusing.
Someone that explains everything as clear as possible and tells you were to put a piece of code.

Someone that tells you how to create a number of codes and tells you exactly what each code does.

Someone that tells you what the diffrence is between JAVA, BOO, C# and C++ (Explaining if codes are longer or
completly diffrent)

Someone that uses the said to be easiest language “Java”

Thanks for reading and please give me links to tutorials that are useful (I want to code independantly)

I think this is a pretty good start. I read through it yesterday and it’s explained pretty well.
Just show syntax really, doesn’t go into anything complicated, but great for understanding what the code means.
(I’m just starting myself so before I read this I had basically no idea what the code did, no I have a meager understanding)
