Directly calling the `hasOwnProperty` method on an object via `Object.prototype` is discouraged. Instead, it’s recommended to use the `hasOwnProperty` method available through the `Object` itself, like `Object.hasOwn(targetObject, propertyName)`. Alternatively, one can utilize the `in` operator with a `hasOwnProperty` check, such as `if (propertyName in targetObject && targetObject.hasOwnProperty(propertyName))`. For instance, to check if an object `myObject` has a property called `name`, the preferred method is `Object.hasOwn(myObject, ‘name’)` rather than `Object.prototype.hasOwnProperty.call(myObject, ‘name’)`. This approach avoids potential issues that can arise when the prototype chain has been modified, ensuring accurate property checks.
This practice safeguards against unexpected behavior if the prototype chain is modified or if the target object has a property named `hasOwnProperty` that shadows the prototype method. By utilizing `Object.hasOwn()` or the `in` operator with an explicit `hasOwnProperty` check, developers ensure code clarity, robustness, and maintainability. This best practice has become increasingly standardized in modern JavaScript environments.
