Any hints on what the correct TypeScript definition for this would be? Basically a 5x5 matrix with empty strings.

const arr = Array(5).fill(Array(5).fill('', 0), 0)

What I tried so far is:

const arr: Array<Array<string>> = Array(5).fill(Array(5).fill('', 0), 0)

but I get Unsafe assignment of type any[] to a variable of type string[][].

One hint I have from VSCode (mouse over the Array definition) is this:

var Array: ArrayConstructor (arrayLength?: number | undefined) => any[] (+2 overloads)

Does this mean that using ArrayConstructor I need to find a way to define the return value?

Any help would be appreciated.
