Type Alias JsonReplacer

JsonReplacer:
    | ((this: unknown, key: string, value: unknown) => unknown)
    | readonly (string | number)[]
    | null

Represents the replacer argument accepted by JSON.stringify

This type unifies the two overloads of JSON.stringify into a single.

Remarks

The function form is called for each key-value pair during serialization.
Returning undefined from the function will omit the property.
The array form acts as a whitelist of keys to include.
Defined explicitly to avoid TypeScript overload inference issues with Parameters<typeof JSON.stringify>[1].
