TObject: {

    fromEntries: <
        const Entries extends readonly (readonly [PropertyKey, unknown])[],
    >(

Grouped export of typed alternatives to Object.keys, Object.entries, and Object.fromEntries.

Type Declaration

entries: <T extends object>(value: T) => ObjectEntry<T>[]
fromEntries: <const Entries extends readonly (readonly [PropertyKey, unknown])[]>(
entries: Entries,
) => { [E in readonly [PropertyKey, unknown] as E[0]]: Widen<E[1]> }
keys: <T extends object>(value: T) => (keyof T)[]

Example

const keys = TObject.keys({ foo: 1, bar: "hello" });
//    ^? ("foo" | "bar")[]

const entries = TObject.entries({ foo: 1, bar: "hello" });
const rebuilt = TObject.fromEntries(entries);
