Script Preparation code:
var array = []; for(var i = 0; i < 100000; i++){array.push(Math.random());}
Tests:
pop
while (array.length > 0) { array.pop(); }
shift
while (array.length > 0) { array.shift(); }
unshift
let a = []; for(var i = 0; i < 100000; ++i) { a.unshift(i); }
push
let a = []; for(var i = 0; i < 100000; ++i) { a.push(i); }
