Sorry, I should explain the problem in brief.
I made a different js file in public/js folder named something.js
But when I uploaded it on shared hosting my website doesn't reflecting that file.
What other file should I change manually.
I am still in learning mode don't know much about webpacking.
@jlrdw
just did What I you said.
I removed mix then uploaded whole website again for no-mistake.
Also checked it in local 2-3 times.
But there is no Change on website.
Considering Cache thing.
[solved] Just changed javascript file name and everything is working fine.
Thanks for all your kind replies.
special thanks to @jlrdw , I tried Everything you said.You are good at your job.
