Hide Javascript Code to Older Browser

Question

Well I think this is kinda dumb but, I wonder if there's any way to hide Javascript code from older browsers without affecting the code for modern browsers.

Yes I know there's the <noscript></noscript> tag to show a message for older browsers, but sometimes very old browsers for any reason show the JS code as text if is not recognized.

I hope you understand.
