Js regexp question match

Question

I am just starting to learn js and I got stuck to regexp at a specific expression. Can you figure out what !![a-z]* will match ? I can't seem to figure this one out.

This is not JavaScript specific.

You should really consider reading how regular expressions work. Have a look at http://www.regular-expressions.info/tutorial.html.

That would match 2 exclamation marks (!) followed any number of letters from a to z.

Two exclamation marks followed by any number (including 0) of characters from a to z.

'!!abcdefgh$asd124123'.match(/!![a-z]*/g)
return ["!!abcdefgh"]

'!!#abcdefgh$asd124123'.match(/!![a-z]*/g)

return ['!!']
