What's the problem with regex?

  There is this expression

  /https:\/\/i\.ytimg\.com\/vi\/([a-zA-Z0-9_-]+)\/maxresdefault\.jpg/i

  
  search for YouTube id follows the link of the picture. I make the expression look for the standard link https://youtu.be/KkcrQTqr9q4
  like this -

  let regexp = /https:\/\/youtu\.be\/\([a-zA-Z0-9_-]+)/;

  but it doesn't work. Where is the mistake

  In the code, you get the video__media element, assign it to the media variable, and then write let url = media.src; . Apparently, this is an ifram, and here is an error, you need to get the value in src like this: let url = media.getAttribute ('src'); should work

  You have escaped the opening parenthesis and it has changed from a service symbol for the beginning of a group into a regular expression symbol.
