Knockout: rateLimit

Out-of-the-box when a Knockout observable changes, any computed observable is notified immediately. In case you want to delay change notifications for a specified period of time, you can use the rateLimit extender.

The rateLimit extender can be applied to any type of observable, including observable arrays and computed observables.

	var name = ko.observable('Bart').extend({ rateLimit: 500 });
	//Name will only change to uppercase after 0.5 seconds
	var upperCaseName = ko.computed(function() {
	return name().toUpperCase();
	});
