Extract Object Entries
Extracts the top-level entries of an object as key-value pairs with proper typing.
extractObjectEntries
The extractObjectEntries function extracts the top-level entries of an object as an array of key-value pairs (tuples) with proper TypeScript typing. It safely handles null and undefined inputs by returning an empty array [].
Function Signature
function extractObjectEntries<T extends GenericObject>(obj: T): Array<ObjectEntry<T>>Parameters
obj(T): The object from which to extract entries.
Return Value
Array<ObjectEntry<T>>: An array of[key, value]tuples representing the enumerable own properties of the object. Returns an empty array if the input isnull,undefinedor non-object value.
Example Usage
playground.ts
Type Safety
Unlike standard Object.entries(obj), which types the keys as string[] and values as any[], extractObjectEntries preserves the literal keys of the object and types the values according to their specific keys using the ObjectEntry<T> utility type.
