Share your code lessons for developers 🔥

Hello, developers! Share you code lessons for developers and I feedback you 🔥🔥🔥

I'll start first!
Recently I started doing small lessons for Node JS developers who would like to try doing something trading.
I've already done two lessons:

https://gaserd.xyz/?go=all/how-create-stock-screener-on-node-js-ep1/

I also did a lesson for my react native developers: https://dev.to/gaserd/small-trick-for-your-app-to-react-native---side-menu-with-overlay-52be

And there is a very old lesson from me on how to make your Google low-cost:
