Function deleteProperty

deleteProperty(
    data: object,
    path: PropertyPath,
    options?: { hasOwnOnly?: boolean },
): boolean
Deletes the property resolved by a property path.

By default, every path segment must be an own property. Set hasOwnOnly to false to permit inherited traversal; when the final property is inherited, the property is deleted from the prototype object that owns it. This explicit opt-in prevents accidental prototype mutation during ordinary use.

Prototype-pollution keys (__proto__, prototype, and constructor) and ECMAScript well-known symbols are rejected at every path segment, matching the mutation hardening applied by safeSet. Non-configurable properties are not deleted.
Parameters
- data: object
  Object containing the property path.
- path: PropertyPath
  Dotted or exact property-key path.
- Optionaloptions: { hasOwnOnly?: boolean }
  Deletion options.
  - OptionalhasOwnOnly?: boolean
    
    Whether every path segment must be an own property; default: true.
Returns boolean
Whether an existing configurable property was deleted.

Throws
If options.hasOwnOnly is not a boolean.
