Benchmark: Shift/Pop - MeasureThat.net

Script Preparation code:

window.n = 100000;

Tests:

shift
arr = Array.from(new Array(n)).map((_,i)=>i) for(let i = 0; i < n; i++){ arr.shift() }
pop
arr = Array.from(new Array(n)).map((_,i)=>i) for(let i = 0; i < n; i++){ arr.pop() }
splice(shift)
arr = Array.from(new Array(n)).map((_,i)=>i) for(let i = 0; i < n; i++){ arr.splice(0, 1) }
splice(pop)
arr = Array.from(new Array(n)).map((_,i)=>i) for(let i = 0; i < n; i++){ arr.splice(n-i-1, 1) }
