includes vs indexOf vs has (v2)

Revision 2 of this benchmark created on April 14, 2023

Setup

const foo = [1, 2, 3, 4, 5, 6];
const bar = new Set([1, 2, 3, 4, 5, 6]);
const fooBig = new Array(10000);
const barBig = new Set();
for(let i=1; i<=10000; i++) {
  fooBig[i-1] = i;
  barBig.add(i);
}

Test runner

const asArrIncludes = foo.includes(6);

const asArrIndex = foo.indexOf(6) >= 0;

const asSet = bar.has(6);

const asIncludesBig = fooBig.includes(10000);

const asIndexOfBig = fooBig.indexOf(10000) >= 0;

const asSetBig = barBig.has(10000);

const asIndexOfBig = (new Set(foo)).has(10000)

const asIndexOfBig = (new Set(fooBig)).has(10000)
