Script Preparation code:

var refArr = ["a", "b", "c"];


var obj = {
    a : 2,
    b: "3",
    c: "yasss",
    //d: "queen",
}

var keys = Object.keys(obj);

Tests:

includes
const rB = refArr.every(elem => keys.includes(elem)) && keys.length === 3;
set
const s = new Set(keys); const rC = refArr.every(elem => s.has(elem)) && keys.length === 3;
in
const rA = refArr.every(elem => elem in obj) && keys.length === 3;
