Benchmark: set includes vs array includes vs or, for two values

Script Preparation code:

const valueArray = [1, 2];
const valueSet = new Set([1, 2]);
const a = 1;
const b = 2;
const c = 3;

Tests:

Array 1
function array1() { valueArray.includes(1); } for (var i = 0; i < 1e5; ++i) { array1(); }
Array 2
function array2() { valueArray.includes(2); } for (var i = 0; i < 1e5; ++i) { array2(); }
Array 3
function array3() { valueArray.includes(3); } for (var i = 0; i < 1e5; ++i) { array3(); }
if 1
function if1() { if (a === a || a === b) {} } for (var i = 0; i < 1e5; ++i) { if1(); }
if 2
function if2() { if (b === a || b === b) {} } for (var i = 0; i < 1e5; ++i) { if2(); }
if 3
function if3() { if (c === a || c === b) {} } for (var i = 0; i < 1e5; ++i) { if3(); }
Set 1
function set1() { valueSet.has(1); } for (var i = 0; i < 1e5; ++i) { set1(); }
Set 2
function set2() { valueSet.has(2); } for (var i = 0; i < 1e5; ++i) { set2(); }
Set 3
function set3() { valueSet.has(1); } for (var i = 0; i < 1e5; ++i) { set3(); }
Inline Set 1
function inlineSet1() { new Set([1, 2]).has(1); } for (var i = 0; i < 1e5; ++i) { inlineSet1(); }
Inline set 2
function inlineSet2() { new Set([1, 2]).has(2); } for (var i = 0; i < 1e5; ++i) { inlineSet2(); }
Inline set 3
function inlineSet3() { new Set([1, 2]).has(3); } for (var i = 0; i < 1e5; ++i) { inlineSet3(); }
Inline const set 1
function inlineConstSet1() { const inlineValueConstSet1 = new Set([1, 2]); inlineValueConstSet1.has(1); } for (var i = 0; i < 1e5; ++i) { inlineConstSet1(); }
Inline const set 2
function inlineConstSet2() { const inlineValueConstSet2 = new Set([1, 2]); inlineValueConstSet2.has(2); } for (var i = 0; i < 1e5; ++i) { inlineConstSet2(); }
Inline const set 3
function inlineConstSet3() { const inlineValueConstSet3 = new Set([1, 2]); inlineValueConstSet3.has(3); } for (var i = 0; i < 1e5; ++i) { inlineConstSet3(); }
