I learned first about Regular Expressions i.e. the finite automata that do a simpler subset of what Regex can do. Learning about this and drawing out the graphs etc, may help commit to memory. Also start using them to help you find and replace stuff in a text editor. They are very handy for converting for example a csv into code.
