This kind of reads like programming philosophy but is a very good read about React hooks.

The Impedance Mismatch

This term is sometimes thrown around, and Phil Haack explains it like this:

One might say Databases are from Mars and Objects are from Venus. Databases do not map naturally to object models. It’s a lot like trying to push the north poles of two magnets together.

Our “impedance mismatch” is not between Databases and Objects. It is between the React programming model and the imperative setInterval API.

A React component may be mounted for a while and go through many different states, but its render result describes all of them at once.

By contrast, setInterval does not describe a process in time — once you set the interval, you can’t change anything about it except clearing it.

That’s the mismatch between the React model and the setInterval API.
