Deep Omit

Requirements

• Export deepOmit as a named and default export. Accept a value and an array of string property names to omit.
• At every depth, remove matching own enumerable string properties from plain objects. Missing keys and duplicate keys are safe.
• Create a new array or plain object for every traversed container, even if no property was omitted. Do not mutate the input or the keys array.
• Visit objects nested inside arrays, preserving array order, length, and holes. Array index strings in keys must not remove array elements. Inputs have no custom array properties.
• Pass through primitives and non-plain objects such as Date, RegExp, Map, and Set using the same value or reference. Functions are values and must not be called.
• Support ordinary and null-prototype plain objects and preserve their prototype. Copy retained properties as writable enumerable configurable data properties, including a literal __proto__ key.
• Ignore inherited, symbol, and non-enumerable properties. Inputs are acyclic data structures with no accessors; descriptor preservation and circular-reference handling are outside scope.

Examples

Input: deepOmit({ id: 1, secret: "x", child: { secret: "y", title: "A" } }, ["secret"]);
Output: { id: 1, child: { title: "A" } }

Input: deepOmit([{ id: 1, hidden: true }, { id: 2 }], ["hidden", "0"]);
Output: [{ id: 1 }, { id: 2 }]

Input: deepOmit({ a: { b: 2 } }, []);
Output: { a: { b: 2 } } // Both plain objects are new copies.
