Benchmark: In vs multiple equality

Script Preparation code:

const tst = "tst_str";
let last_res;
const arr = ["str", "str2", "str3", "str4"];
const obj = {"str": true, "str2": true, "str3": true, "str4": true};
const mp = new Map([["str", true], ["str2", true], ["str3", true], ["str4", true]]);
const st = new Set(["str", "str2", "str3", "str4"]);

Tests:

Eql
const tst = "tst_str"; let last_res; for (let i = 0; i < 1000; i++) { last_res = tst === "str" last_res = tst === "str2" last_res = tst === "str3" last_res = tst === "str4" }
Arr
const tst = "tst_str"; const arr = ["str", "str2", "str3", "str4"]; let last_res; for (let i = 0; i < 1000; i++) { last_res = arr.includes(tst); }
Obj
const tst = "tst_str"; const obj = {"str": true, "str2": true, "str3": true, "str4": true}; let last_res; for (let i = 0; i < 1000; i++) { last_res = tst in obj; }
Map
const tst = "tst_str"; const mp = new Map([["str", true], ["str2", true], ["str3", true], ["str4", true]]); let last_res; for (let i = 0; i < 1000; i++) { last_res = mp.has(tst); }
Set
const tst = "tst_str"; const st = new Set(["str", "str2", "str3", "str4"]); let last_res; for (let i = 0; i < 1000; i++) { last_res = st.has(tst); }
