Tell us what’s happening:

So the output & preview is working exactly as it should. But it’s not passing the tests… any hint as to why???

you should be using a different event type. What if I paste text in the box? it will not work

3

I’ve changed it to “input” and although its passed some extra tests im still failing quite a few that should be passing.

I’m not sure how to test for strings that are in the $1. I’ve tried to google it but I cant find a solution. Do I need to change my approach???

4

if I write ## title 2 I get an h1, that is not correct

Thankyou! Completely missed that. Fixed that.

Any suggestion for how I can turn the $1/2 into strings to check for regex?

6

if you use a callback as second argument of replace instead of a string, you should be able to do that

7

okay so I keep running into the same issue. Do i need to use a loop or something to re-check the string??

Super confused as to how to pass the tests where there is a regex within the regex!
