Tell us what’s happening:

I’m stuck on this test :

Failed: 38. When the value of #markdown-input is ![alt-text](image-source) followed by ![alt-text-2](image-source-2) on a new line, convertMarkdown() should return <img alt="alt-text" src="image-source"><img alt="alt-text-2" src="image-source-2">.

Although I’m passing this one :

Passed: 42. When the value of “#markdown-input” is [link text](URL) followed by [link text 2](URL 2) on a new line, “convertMarkdown()” should return <a href="URL">link text</a><a href="URL2">link text 2</a>.

When my input is :

![alt-text](image-source)
![alt-text-2](image-source-2)

[link text](URL)
[link text 2](URL2)

The output in #html-output is

<img alt="alt-text" src="image-source">
<img alt="alt-text-2" src="image-source-2">

<a href="URL">link text</a>
<a href="URL2">link text 2</a>

I have tried adding .replace(/\n(?=<img)/g, "") to ‘manually’ replace line breaks after img, but I still fail 38.

The only difference between regexImg and regexLink is ^!, I don’t understand why one passes the test and the other not.

Nevermind, found it.
I needed to remove the ^ anchor, at the beginning of regexImg
