Lesson 6 — Objects
Objects
An object groups related data as key: value pairs inside curly braces, and you read a value with a dot: user.name. It describes one thing with many properties.
Why it matters: objects model real-world items — a user, a product, settings — and are the shape of almost all web data (JSON).
Tip: you can also read a property with brackets, user["name"], handy when the key is in a variable. Assigning to a new key (user.age = 20) adds it.
