I think what you are after is encrypting/obfuscating javascript code; you cant avoid but send your JavaScript code to the client.
The best you can do is obfuscate it, which is essentially making it harder to humanly read it. and here the SO reference if you want to go down that path
How can I obfuscate (protect) JavaScript?
I am not sure why you want to do this, is it to protect some of your own code, if so then its ok, but if you are planning on putting sensitive data such as usernames/passwords embeddeed into your javascript then please don’t do so, its ok to go to the server to fetch stuff better being secure 🙂 happy coding.
