String.includes
var testString = testArray.join(','); const testStrFirst = 'foo'; testString.includes(testStrFirst); const testStrSecond = 'bar'; testString.includes(testStrSecond); const testStrNotMatch = 'baz'; testString.includes(testStrNotMatch);
Object Hash-map
var objectHash = testArray.reduce((acc, key) => {acc[key] = true; return acc;},{}); const testStrFirst = 'foo'; objectHash[testStrFirst]; const testStrSecond = 'bar'; objectHash[testStrSecond]; const testStrNotMatch = 'baz'; objectHash[testStrNotMatch];
