requestIdleCallback

Last updated on : 2023-03-20

Note:
requestIdleCallback shows a browser compatibility score of 75. This is a collective score out of 100 to represent browser support of a web technology. The higher this score is, the greater is the browser compatibility. The browser compatibility score is not a 100% reflection for every browser and the web technology support. However, it does give you an estimate on how much you should rely on a particular web technology in terms of browser compatibility.

Overview

This API provides a mechanism for executing JavaScript code in a browser context when the browser is idle. The API is designed to reduce the need for polling, allowing developers to queue up work to happen while the browser's resources are otherwise occupied.
