    TL;DR: you won't.

    This website is rather a good memo regarding each language's foundations:

    • what's its general purpose?
    • how to write core instructions, such as functions, loops, conditional structures?

    I find this kind of reminder quite useful when it comes to documentation languages (e.g. TeX, Markdown)
