Site looks cool. Good to see you've made it interactive. Seems like you are supporting JS flavor, that should be mentioned prominently. Suggestions for the cheatsheet: 1) Multiline example regex is missing the anchors 2) Negative lookbehind should be `(?<!)` not `(?!)` 3) `+` and `*` examples are using `()` around a character, which isn't needed (the `?` example doesn't use it)
