I'll explain what I need to do and what I'm doing with it. My ask is for an advice on how to improve this process.

I'm a tutor in a ReactJs course and I need to review my tutees apps. So, I've trying 2 things. First I was cloning the repo on a random folder in my pc, then installed the node_modules from the app and the ran the app. Then I deleted the whole folder and continue with the next one (time consuming). Then I started to leave the folders and when I had to review anything new from the same student I did a fetch/pull to obtain the new commits from that repo, but, I don't know why, somehow it started draining my ram and my pc was so slow (I have 20 apps to review, so 20 repos, 20 node_modules, not running at the same time, I kill the server before reviewing the next one, but still..)

I'm not really sure if I'm explaining myself. I could review only the code, but I really prefer to run each app to give feedback, make sure to review the console.. actually see how the app is looking like. So please, if you have any advice for me to improve this process I would really appreciate it. I believe I'm doing it all wrong and there are ways to do this better.

Thanks in advance.
