Script Preparation code:

var data = "aaaa";
var falseData = "bbbb";
var matchers = [
	...Array.from({length: 30}).map((_, i) => "dummy" + i), 
    "aaaa", 
    ...Array.from({length: 30}).map((_, i) => "dummyII" + i)];
var regex = new RegExp(`(^|\\.)(${matchers.join('|')})$`);

Tests:

indexOf
const res = matchers.indexOf(data) >= 0 const fRes = matchers.indexOf(falseData) >= 0
findIndex
const res = matchers.findIndex(key => key === data) >= 0 const fRes = matchers.findIndex(key => key === falseData) >= 0
Regex
const res = regex.test(data); const fRes = regex.test(falseData);
includes
const res = matchers.includes(data) const fRes = matchers.includes(falseData)
