Benchmark: arr reverse v2 - MeasureThat.net

Script Preparation code:

var size = 1000;
var descend = true;

Tests:

for
let arr = [] for(let i=size; i >= 1; i--){ arr.push(i) }
for reverse
let arr = [] for(let i=1; i <= size; i++){ arr.push(i) } arr.reverse()
for Composite
let arr = [] let [start, end] = descend ? [size, 1]: [1, size] let step = descend ? -1 : 1 for (let index = start; (descend ? index >= end : index <= end); index+=step) { arr.push(index) }
for Composite perf fn
let arr = [] let [start, end] = descend ? [size, 1]: [1, size] let step = descend ? -1 : 1 let compare = descend ? (index, end) => index >= end : (index, end) => index <= end for (let index = start; compare(index, end); index+=step) { arr.push(index) }
for Composite perf if
let arr = [] let [start, end] = descend ? [size, 1]: [1, size] let step = descend ? -1 : 1 if(descend) { for (let index = start; index >= end; index+=step) { arr.push(index) } } else { for (let index = start; index <= end; index+=step) { arr.push(index) } }
