How come this RegEx isn't working quite right?

Question

I have this RegEx here:

/^function(\d)$/

It matches function(5) but not function(55). How come?

Answer 1

The other posters are correct about the +, but what language are you using for to parse the regular expression? Shouldn't you have to escape the ()? Otherwise it should capture the digit(s).

I would think you would need...

/^function\(\d+\)$/
