here's a load of fun regex crosswords - https://regexcrossword.com/
and an extra jumbo one - https://gregable.com/2015/12/regular-expression-crossword-puzzle.html
this is a good tool for writing, testing and seeing useful snippets of regex - http://regexr.com/
online regex tester and debugger - helpful for breaking down a regex, identifying matched groups, testing substitutions etc. - https://regex101.com/
good tutorials of some of the concepts not covered well elsewhere, e.g. greedy & lazy quantifiers - http://javascript.info/tutorial/regular-expressions-javascript
a very thorough reference you may need when writing more sophisticated expressions - not limited to javascript - http://www.regular-expressions.info
RegexOne is a tutorial that starts simply and gets a little more complex. Good for beginners. Note: it doesn't deal with regex in the context of js, just raw regular expressions:
http://regexone.com/
I would second regexone. I found it a great resource for learning regex originally..
A nice little "RegEx game" to test your the learning - http://regex.alf.nu/
I see @tomhuhges has also pointed out some RegEx games. Maybe we could make two sections? One for learning and one for applying/games?
A really good online tutorial suited to different levels (beginner, intermediate & advanced) it has a full range of tutorials ranging from the fundamentals to more advanced regex stuff and also has language specific sections(JS, Ruby etc) http://www.rexegg.com/
An environment in which to test, save and browse Regular Expressions
