import { type MultidimensionalArray } from "https://deno.land/x/actionify@0.3.0/src/deps/types.ts";
Creates a type that represents a multidimensional array of the given type and dimension.
Use-cases:
- Return a n-dimensional array from functions.
- Declare a n-dimensional array by defining its dimensions rather than declaring
[]
repetitively. - Infer the dimensions of a n-dimensional array automatically from function arguments.
- Avoid the need to know in advance the dimensions of a n-dimensional array allowing them to be dynamic.

import type {MultidimensionalArray} from 'type-fest';
function emptyMatrix<T extends number>(dimensions: T): MultidimensionalArray<unknown, T> {
const matrix: unknown[] = [];
let subMatrix = matrix;
for (let dimension = 1; dimension < dimensions; ++dimension) {
console.log(`Initializing dimension #${dimension}`);
subMatrix[0] = [];
subMatrix = subMatrix[0] as unknown[];
}
return matrix as MultidimensionalArray<unknown, T>;
}
const matrix = emptyMatrix(3);
matrix[0][0][0] = 42;
