Describe an object

Objects group related properties.

A type alias names an object shape. Properties can have different types. Structural typing means matching shapes are compatible; it does not validate JSON from a server.

A contact card groups a name and age into one record.

Read the example

type Learner = { name: string; points: number };
const learner: Learner = {name:"Ada", points:50};
console.log(learner.name);

Ada

Your challenge

Return "NAME has POINTS points" using input.name and input.points.

Common trap

input.name and input["name"] work; input[name] looks up the value of a variable called name.
