rename

Renames selected own enumerable keys and copies every other key unchanged.

const transform = rename({user_id: 'id', full_name: 'name'});

transform({user_id: 1, full_name: 'Ada', email: 'ada@example.com'});
// {id: 1, name: 'Ada', email: 'ada@example.com'}

The input is not mutated. String and symbol keys are supported. The operation is shallow, and values keep their original references.

The Renamed utility type represents the same key mapping at the type level.
