🎲 Features

1. Debounces rapid function calls and preserves this context
2. Fully type-safe (TypeScript-first)
3. Works in Node & browser environments
4. Zero dependencies
5. Minimal Footprint
6. Unit-Tested using Jest with fake timers to verify

💻 Usage

/* node modules */
import { microBounce } from 'micro-bounce-js';

/* your fn */
function aSimpleLogger(message: string): void {
  console.log(messsage);
}

/* create the debounce instance */
const dLogger = microBounce(aSimpleLogger, 500);
dLogger('Hey there. How you doing?');
