Function throttle

Throttles a function. Callback only allowed to run after minimum of intervalMinMs.

Example: Only handle move event every 500ms

const moveThrottled = throttle( (elapsedMs, args) => {
 // Handle ar
}, 500);
el.addEventListener(`pointermove`, moveThrottled)
Copy

Note that throttle does not schedule invocations, but rather acts as a filter that sometimes allows follow-through to callback, sometimes not. There is an expectation then that the return function from throttle is repeatedly called, such as the case for handling a stream of data/events.

Example: Manual trigger

// Set up once
const t = throttle( (elapsedMs, args) => { ... }, 5000);

// Later, trigger throttle. Sometimes the callback will run,
// with data passed in to args[0]
t(data);
