Question

I’m having some difficulties converting my python regex to javascript. If my needle was ‘apple’ or ‘#apple’, both case insensitive, I’d want to match any of the following from a haystack:

'apple', '#apple', ' apple', ' apple ', '#orange#apple'

Here is my python regex:

r"\b#?apple\b"

My feeble attempt at converting this to javascript was :

/\b#?apple\b/i

But it doesn’t seem to work. Can anyone help?

Answer 1

Put the word boundary \b after the # char:

/#?\bapple\b/
