How to Use Tuples in TypeScript

Tuples extend the capabilities of the array data type. With tuples, we can easily construct special kinds of arrays, where elements are of fixed types with respect to an index or position. Due to the nature of TypeScript, these element types are known at the point of initialization. With tuples, we can define the data type that can be stored in every position in an array.

What are tuples?

Tuples are like advanced arrays with extra features that ensure type safety, particularly when we need to account for a list containing a fixed number of elements with multiple known types.

The major difference between arrays and tuples is that when we assign values to a tuple, these values must match the types defined in the tuple declaration in the same order. On the other hand, arrays can support multiple types with the ...
