# Unused JS Code

 * The developer tools of Chrome shows me under “coverage” the files with unused
   code. The number 1 file is comming from SmartSlider3
 * See the screenshot

 * See the file
    [https://dlgo.de/75b5d70758c58f7c2b50b6812b20cef3.js](https://dlgo.de/75b5d70758c58f7c2b50b6812b20cef3.js)
 * This is a combined file. For sure I can uncombine it, but this does not reduce
   the unused code in total.
    What can I do to get rid of this 51,9% unused code?
   10% unused is ok, but not that much as shown here.

 * Hi [@a223123131](https://wordpress.org/support/users/a223123131/)
 * We’re working on improving this, part of the Web Vital Performance improvements
   we’re planning based on your previous topic:

 * You see… there is a huge pressure (not only by me) on Web Vital Performance
 * In your changelog you are showing that you are working on CLS. The fokus here
   is very important. The 51,9% in this js file is a different point of Web Vital,
   that’s why I highlighted it here. This js is by far the file with the most unused
   code I have.

 * You see that your js is #1 and the #2 is half of the unused bytes (and I have
   a huge number of plugins installed). So beside CLS improvement the unused code
   improvement should be #2 in your Web Vital improvements.
 * Hope to see the first improvements in the first half of January 😉
