Type Alias NestedArray<T, S>

NestedArray: S extends readonly []
    ? T
    : S extends readonly [infer N, ...(infer Rest)]
        ? N extends number
            ? Rest extends Shape ? TupleOf<NestedArray<T, Rest>, N> : never
            : never
        : never

Nested array type based on shape

Converts a shape tuple into the corresponding nested array type. Used for type-safe tensor creation from JavaScript arrays.

Type Parameters

T
Element type
S extends Shape
Shape tuple

Example

type Scalar = NestedArray<number, readonly []>;           // number
type Vector = NestedArray<number, readonly [3]>;          // [number, number, number]
type Matrix = NestedArray<number, readonly [2, 3]>;       // [[number, number, number], [number, number, number]]
