Function filter

filter<K extends PropertyKey, V>(
record: Readonly<Record<K, V>>,
predicate: (value: V, key: K) => boolean,
): Partial<Record<K, V>>
Keep only entries for which predicate returns true. Result is typed Partial since keys may be absent.

Dual API — works data-first or curried for use in pipe.
Type Parameters
- K extends PropertyKey
- V
Parameters
- record: Readonly<Record<K, V>>
- predicate: (value: V, key: K) => boolean
Returns Partial<Record<K, V>>
Example
```
pipe(
    { a: 1, b: 2, c: 3 },
    Records.filter((v) => v % 2 === 1),
  )
  // { a: 1, c: 3 }
```
