Take a look at Use hooks libraries for examples of code that you may want to have portability with (this is they typescript one because its the one I've used) One of the simplest examples is "useToggle" which just sets a state variable to true or false. Not hard to write in a class component but it's still stuff that you may end up writing a lot. A lot of similar ones are click and event handlers that need to be cleaned up after the component is unmounted. useIsMounted is one I use a lot too to ensure I'm not trying to write state on an API callback once a component is unmounted. You could add each of these to a class with an hoc and end up with withToggle(withIsMounted(withUseMediaEvent(MyComponent))) but that tends to be a bit of a mess. https://usehooks-ts.com/ https://usehooks-ts.com/
