Ok, so, you might know about JavaScript regular expressions. Well, here is a tutorial about them, but written by a 13 year old, so it isn't actually any good!
Regular expressions go between /
characters. Here is an exampe, /hi/
.
Ok, now then. Let's learn how to match the string abc
. Well, that's quite simple.
/abc/
. Yey! So putting letters next to each other makes them match one after the other.
Ok, now, after the second /
we can put a g
to make it match globally, that is, we can extract abc
from xyzabcghi
.
