Performance tests for mobx and redux

Demo: https://schontz.github.io/mobx-redux-perf/

I wanted to test some perf differences for redux and mobx.

So far, I am testing updating long lists of data. mobx performs really well with no optimizations. Redux was very slow out the gate, and after some targeted performance ops it is performs about the same. Maybe someone with more redux knowledge can speed it up, but I'm liking the following:

1. mobx "just works" with great perf.
2. You can write regular JavaScript with better modularization (though createSlice helps a lot).
3. You can maintain your state infrastructure outside of redux/provider land, which makes interacting with various services much easier (think: React is just a view layer).

Available Scripts

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
