this type here uses recursion to create a type of an array with a fixed length. use case example: let arr:ArrayWithLength<3 /*the desired length*/, number /*the desired type of the array*/>; //will result with [number, number, number]

To declare a Fixed-length Array in TypeScript you can use a Tuple. Tuple types allow you to specify the types for each element in the array and, importantly, define a fixed number of elements in a specific order. In this article, we are going to learn how to declare a fixed-length array in TypeScript.

Fixed-length arrays are critical in situations where the data structure’s size must be known at compile time for correctness and performance reasons. TypeScript’s tuple types offer a way to model fixed-length arrays, although they do not enforce length at runtime.

First, we use the trick introduced in Typescript 2.7 for fixed size tuples. The length of an array has a numeric literal type. We need it to match tuples of exact size.

You could return a tuple instead of an array: type array_of_4 = [number, number, number, number]; var myFixedLengthArray :array_of_4 = [1,2,3,4]; // the tuple can be used as an array: console.log(myFixedLengthArray.join(','));
