debounce.tsx

// Debounce calls a function after N amount of time passes since its last call
// Example, debounce(callback, 100) called every 10ms. Callback will never run.
// Example, debounce(callback, 100) called 30 times in 10ms, then not called again. Callback will run 100ms after the last call.
