I switch back and forth between js(Vue) and Java and get them mixed up a alot which slows me down because I have to look up conventions. Any tips on managing multiple Lang's mentally

You get use to it over time.

I generally have to switch between PHP, Java, Python and JavaScript on a daily basis, all's different projects as well, being able to context switch with ease is a difficult thing.

If possible, use different coding styles between the two, this will at least train your brain in having something to seperate them apart.

@C0D4 thx I'm trying different ide color schemes rn to see if that helps

@iamroot could work if you only open specific files in the right place.

I guess it depends how you seperate things that matters and stick to it.

I have to keep switching between c#, vb, vb .Net, javascript and occasionally python or php. Even if you get used to it, you'll keep wondering why a semicolon is an error sometimes, until you realize you are in a different language. But I do believe is positive to expose yourself to different languages

I open Java files in IDEA and nearly everything else (JS, Reason, Bash) in VSCode and never had that problem.

To me, everything looks different enough to mentally switch between them.

Use a different theme in the IDE. Brain will make connections
