Obfuscated JavaScript

The result will appear here

Obfuscation slows people down; it does not hide secrets. Never ship API keys or passwords in client-side code.
“Rename top-level names” breaks code that other scripts call by name (globals). Leave it off for libraries and plain script tags.
Test the obfuscated file before deploying, and keep the original source in version control.
