It depends on what you already know about programming. There is a distinct line between learning TorqueScript and learning how to program all together. If you're learning how to code for the first time, I would recommend you go to something like
Codecademy and learn the basics of coding there. It focuses on JavaScript (and Python recently IIRC) but the two have a similar syntax so if you learn JavaScript, you'll be able to learn TorqueScript rather easily. If you already have a basic understanding of programming (knowledge of a language in the C family would be best),
Coding Help has some excellent resources.
