Answer 2

Web Worker

           

Web worker is a JavaScript running in the background, without affecting the performance of the page.

It is designed as a Java which does't low down the speed of specific website. For checking website uses Web worker or not we can use Java inspector. By which we can see the web worker programming.

                 

When we link our website by cludflare, then Cloudfare automatically add a web worker to our website.

Web worker does't low down our speed. Because web worker work is browsed in DNS server.

Mostly of websites have Web worker. But website which don't have any kind of web worker, that website speed doesn't increases and decreases.
