Understanding React Concepts in 3 Minutes or less

I'm currently enrolled in Epic React by Kent C. Dodds and thus learning super much about React. I noticed that I need to take notes to improve retention and also to have a place where I can access the knowledge in a condensed matter.

I decided to put the principle learning in public by Shawn Wang into practice and will create short blog posts outlining a specific topic of the React ecosystem.

To be a valuable source of knowledge in the future for me, I will keep each article short and adhere to the following guidelines:

3 minutes or less (less than 600 words, with an average reading speed of 200 words per minute)
Explain a concept concisely, but well enough that the main points are covered
Provide actionable code samples to use when looking for answers while developing

I will be doing this mainly to facilitate my personal learning but if it helps anybody else it's even better!
