I'm documenting the .match() method for JavaScript, there are others.

• / by itself indicates the beginning and the end of the regex
• /^ combined with $/ means “ match the entire string” (rather than matching substrings that begin and/or end somewhere in the middle)
• the i suffix is a modifier indicating that the match should be done in a case-insensitive manner
• [a-z0-9\-] matches a character which is either a number, letter or dash (works for capital letters because of the i at the end
• the + indicates the match one or more of whatever came before
• if you put a caret (^) inside of the match expression capturer thingamajig, it reverses the meaning
