Is a script obfuscated and when should scripts be encrypted?

Question

JavaScript

Link to the site script https://egb.com/assets/app_lib-b47a407d3887f70951f... .
And tell me when and in what cases it is necessary to use js code cryptography? So I read that it is possible to crypt CSS and HTML, I would like to know if there is a need? In what cases and why?

Answer 1

This one is not obfuscated. From this code, all extra spaces were simply removed and some code constructs were slightly reduced in order to reduce the size of the final file.
Obfuscation is used to complicate the decoding of algorithms; however, if necessary, you can still understand the algorithm itself, so usually there is no point in such coding, except perhaps "fool-proof". If someone needs to decipher the algorithm of work, he will do it.
