Executions per second
Object Hash-map
35047096.0 Ops/sec
Array.indexOf

Script Preparation code:
var testArray = ['a','b', 'c','d','e','f','g','h','i','j', 'k', 'l','m','n' ,'bar','o', 'p', 'q', 'r', 's','t','u', 'v','w','x','y', 'z']; let i =0; var objectHash = testArray.reduce((acc, key) => {acc[key] = i++; return acc;},{});
Tests:
Object Hash-map
const testStrFirst = 'foo'; objectHash[testStrFirst]; const testStrSecond = 'bar'; objectHash[testStrSecond]; const testStrNotMatch = 'baz'; objectHash[testStrNotMatch];
Array.indexOf
const testStrFirst = 'foo'; testArray.indexOf(testStrFirst); const testStrSecond = 'bar'; testArray.indexOf(testStrSecond); const testStrNotMatch = 'baz'; testArray.indexOf(testStrNotMatch);
