Script Preparation code:

var a = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19"];

Tests:

Array.indexOf()
a.indexOf("12") >= 0
Array.includes(value)
a.includes("12")
Array.includes(function)
a.includes((v) => v === "12")
Array.find()
a.find((v) => v === "12")
Array.some()
a.some((v) => v === "12")
Array.filter()
a.filter((v) => v === "12").length > 0
Loop
for (var i = 0; i < a.length; i++) { if (a[i] === "12") { return true; } } return false;
$.inArray()
$.inArray("12", a)
_.includes()
_.includes(a, "12")
