i've been working in legacy code have functionality should return random item array , see following expression: array[math.random() * arr.length | 0] my first impression try undestand the | operator can't figure out how work. test expression in chrome console , see returns valid index this: let array = [1,2,3,4] for(let = 0; < 5000; i++){ console.log(array[math.random() * arr.length | 0]); } how "math.random() * arr.length | 0" works return random index array? math.random() returns number >= 0 , < 1. * arr.length returns number >= 0 , < arr.length, yet can't used index, because have fractional part | 0 coerces left expression integral number applies bitwise or number zero, other number this said, makes work implicit conversion (called coersion) in operator | .

there requirement monitor pool of 20 servers. each servers create vhds periodically perform xyz tasks , unmounts them safely. vhd mounting , unmounting scripts legacy ones , written in batch diskpart.exe , not powershell more ever stale vhds start pile in these servers on period of time (a week or several reasons). there way force unmount vhd discarding changes periodically part of cleanup routine? diskpart not effective ejecting drive or unmounting disk manager not clean approach , throws errors if vhd not unmounted restarting server cleanest way not preferred is there way force unmount vhd drives via powershell or inbuilt win10 tools when .vhdx file not available. preferred approach use powershell script on diskpart avoid these kind of issues?
