Script Preparation code:
var arr = []; for (let i = 0; i < 1000000; i++) { arr.push(i); }
Tests:
slice/0
for (let i = 0; i < 1000; i++) { const v = arr.slice(-1)[0]; }
length - 1
for (let i = 0; i < 1000; i++) { const v = arr[arr.length - 1]; }
slice/pop
for (let i = 0; i < 1000; i++) { const v = arr.slice(-1).pop(); }
slice/shift
for (let i = 0; i < 1000; i++) { const v = arr.slice(-1).shift(); }
