Description: The ‘Object.isSealed’ method is a function in JavaScript that allows determining whether an object is sealed. An object is considered sealed if no new properties can be added to it and existing properties cannot be removed. However, existing properties can still be modified. This method returns a boolean value: ‘true’ if the object is sealed and ‘false’ otherwise. The ability to seal objects is an important feature in programming, as it allows protecting the structure of an object and preventing unwanted changes. This is especially useful in environments where data integrity is crucial. By using ‘Object.isSealed’, developers can implement design patterns that promote immutability and data security, resulting in more robust code that is less prone to errors. In summary, ‘Object.isSealed’ is a valuable tool for managing the mutability of objects in JavaScript, providing additional control over the manipulation of their properties.
