Working with Tuples

Snippet

A tuple is a TypeScript type that allows you to express an array with a fixed number of elements whose types are known, but need not be the same.

snippet.ts
typescript
const employee: [number, string, boolean] = [1, "Jane Doe", true];
const id = employee[0];
const name = employee[1];

Breakdown

const employee: [number, string, boolean]

Defines a tuple that must contain exactly a number, a string, and a boolean in that order.

[1, "Jane Doe", true]

Initializes the tuple with values matching the defined types.
