Inspired by kona's YouTube CPU Tamer

Description

This is for all kinds of YouTube applications, including main page, embedded video, and live chat.

- Faster
- More Stable
- Lower Battery Consumption

Note1: This hijacks to setTimeout, setInterval, clearTimeout, clearInterval
Note2: This uses setInterval(..., 250ms) instead of requestAnimationFrame for background running.

Remarks

This userscript hijacks setTimeout & setInterval leading different browser behaviors as follows:

Case 1

let f=function(){console.log('hello world')};
setTimeout(f,100);setTimeout(f,100);setTimeout(f,100);
Native: print out "hello world" 3 times.
Modified: print out "hellow world" 1 time.

Case 2

let f=function(){console.log('hello world')};
setTimeout(f,100);setTimeout(f,110);setTimeout(f,120);
Native: print out "hello world" 3 times.
Modified: print out "hellow world" 1 ~ 3 time(s) depending on execution time of f and AnimationFrame's segregation;

Case 3

let f=function(){console.log('hello world')};
setTimeout(f,100);setTimeout(f,200);setTimeout(f,300);
Native: print out "hello world" 3 times.
Modified: print out "hello world" 3 times.
