Benchmark: Bitwise Truncation Methods

Script Preparation code:

"use strict";
const arr = Array.from({length: 1000}, (function(){return Math.random()*1000}));

Tests:

~~num
"use strict"; let x = 0; for (let i=0; i<1000; i++) { x = ~~(arr[i]); }
num | 0
"use strict"; let x = 0; for (let i=0; i<1000; i++) { x = (arr[i]) | 0; }
num << 0
"use strict"; let x = 0; for (let i=0; i<1000; i++) { x = (arr[i]) << 0; }
num >> 0
"use strict"; let x = 0; for (let i=0; i<1000; i++) { x = (arr[i]) >> 0; }
num >>> 0
"use strict"; let x = 0; for (let i=0; i<1000; i++) { x = (arr[i]) >>> 0; }
