@iliakan Why? it's not polite, close PR without explanation.

[iliakan]

First, thanks for the PR.

This section is about regular expressions. So more details about str.split seems extraneous.

Usually when I ask people to fix their PRs, they don't do that.
That's why I took the first change (array quotes) and applied it in the commit 6418344.

Sorry for any offence, and thanks for the contribution!

[behnammodi]

Thanks for the response, but I think we can add a refer-link for str.split

[iliakan]

We could, but this method is so obvious...

@iliakan Ok man 😀 , you're right
