I got a new idea : I'm writing some python scripts to help me in my projects at school, I think it will help me a lot !

But I would like to code some scripts for my side-projects that are made using full JS.
NodeJS + Express + Sequelize for the Web API and ReactJS and HighlightJS for the client.

I would like to know if you could give me some ideas of scripts I could write for these JS side-projects ?
