// THE POINT THIS WEEK
Objects. Access and update. Looping objects. Nesting arrays and objects.
// TALKING POINTS
Objects hold shape
- An object stores named properties: person.name, person.age
- Dot notation reads and writes; keys are labels, values are anything
- Arrays for order, objects for structure; real data nests both
Nested data is normal
- An array of objects is the workhorse of real software
- contacts[2].email reads: third contact, their email
- Draw the shape on paper before writing the code that walks it
> TREASURE HUNT WEEKThe Nested Vault opens today: student door · foreman key. Badge Q. Run it in the build block or assign as the week's warm-down.
