An object is like an array, but you set the keys too, instead of 0, 1, 2, 3, etc.
For example, say you had an array of ages: [24, 57, 25, 12]. You clearly can't see what the person is, so we can turn this into an object:
{
'Bob': 24,
'Earl': 57,
'Maria': 25,
'Adam': 12
}
(Note: these are just random names and ages)
