Why do we need to use *?

I'm confusing.What would it do without *?

$('a').not('[href*="my-domain.com"]').attr("target", "_blank");

Are you asking about an asterisk symbol ("*")? I don't see one in that line of code, perhaps it's being lost because the code is not formatted.

Always use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:   Or watch this video on code formatting.

I'm going to guess that you intended to show "*=" in the attribute selector. That symbol means "contains", so it would match any value that contained the string shown. But just a plain "=" symbol means "equals", and would only match if the value was exactly the same as the string shown.
