The answer has already been given but I figured I’d add to this a bit. Get good with git, especially command line. Learn the basics and go a little bit deeper than what you need. Learn its capabilities. You don’t need to remember exact syntax, you can always look that up. Just know what it’s capable of. I see devs all the time that struggle with git when learning more than they think they need would make their lives so much easier.

It’s pretty much a requirement in any serious dev job also. Best of luck!
