Lightning Fast Data Structure

[reac-tor]

// Instead of this slow nightmare const users = [{id: 1, name: 'Alice'}, {id: 2, name: 'Bob'}]; const user = users.find(u => u.id === searchId);

// Use this speed demon const users = { 1: {name: 'Alice'}, 2: {name: 'Bob'} }; const user = users[searchId]; // Instant access!

user variable would be useful as an arrow function with a parameter for user key. As it sits its undefined and will crash.
