Installation

$ component install component/debounce

Or in node:

$ npm install debounce

Example

var debounce = require('debounce');
window.onresize = debounce(resize, 200);

function resize(e) {
  console.log('height', window.innerHeight);
  console.log('width', window.innerWidth);
}

API

debounce(fn, wait, [ immediate || false ])

Creates and returns a new debounced version of the passed function that will postpone its execution until after wait milliseconds have elapsed since the last time it was invoked.

Pass true for the immediate parameter to cause debounce to trigger the function on the leading edge instead of the trailing edge of the wait interval. Useful in circumstances like preventing accidental double-clicks on a "submit" button from firing a second time.
