How do i deobfuscate Javascript? [closed]

so i’m having this blogger template and i’m trying to reverse engineer it. But,the javascript code is Vague, or encoded to whatever blackmagic it is, could someone help me in removing the curse.

i tried using online DEobfuscators but they don’t seem to work (or i didn’t know how to use them). Here is the code, please tell me if it is possible to decode/unencrypt it.

this is not from “view page source” tab, it’s from the theme editor

Thanks

Tried asking GPT, using online remove the coding, nothing seemed to work, i really don’t know what to do, if there is something i can know i’d be keen to learn about it.
