Object Map

Requirements

• Implement objectMap(object, iteratee). Return a new plain object with the same own enumerable string keys and values returned by the callback.
• Call iteratee(value, key, originalObject) exactly once for each included key, in Object.keys order. Skip inherited, non-enumerable, and symbol properties.
• Preserve keys even when the callback returns undefined, null, or another falsy value. Empty input returns a new empty object.
• Do not mutate the input or clone callback results. Support null-prototype inputs and special own keys such as __proto__ without changing the output prototype.
• Assume a non-null record object and a valid callback that does not mutate it. Propagate callback errors.

Examples

Input: objectMap({ a: 1, b: 2 }, (value) => value * 2)
Output: { a: 2, b: 4 }

Input: objectMap({ a: 1, b: 2 }, (value, key) => key + ':' + value)
Output: { a: 'a:1', b: 'b:2' }

Input: objectMap({}, (value) => value)
Output: {}
