Sometimes you forget features of a language and you look them up. We want to stop doing that. We want to be able to code in a language as free and as easily as we can speak.
You can do this with daily programming exercises.
Usually you only excercise what you need when you work on a project, but projects don't use alot of features of a language that you should know by heart!
This is the vanilla JavaScript folder. Open that folder and follow the instructions. Node.js will be needed.
The React folder has various small React exercises based on using Hooks and Redux Core.
Other languages will be added in the future.
