Debounce vs. Throttle (Rx.js v5)

debounce-vs-throttle.js

// Just look the console output.
// NOTE: Requires Rx.js v5.x

var mousemoves$ = Rx.Observable.fromEvent(document.body, 'mousemove');

// Events will be fired at most once every 200ms
var throtttled = mousemoves$.throttleTime(200);

// The latest event will be fired after 200ms. This means that if you are continually 
// moving your mouse around the browser, causing mousemove events, none of them will
// show up until you stop moving the mouse for at least 200ms, at which point the 
// last mousemove will be allowed through.
var debounced = mousemoves$.debounceTime(200);
