→ Testing debounced actions: filtering on key up
This example showcases filtering a tree of options based on user input. In order to not re-calculate the tree unneccessarily, we debounce tree recalculation by a certain time. Debouncing in this example means: "Only recalculate the tree when there was no keyup event within 250 milliseconds".
The example project was bootstrapped with Create React App. The usual npm install, npm start, npm test apply.
