Can you explain the use of object wrappers with examples?

They provide useful methods for working with primitive values. For example, the Number object provides methods like toExponential().
When a property is accessed on a primitive value, JavaScript automatically wraps the value into the corresponding wrapper object and accesses the property on the object instead. However, accessing a property on null or undefined throws a TypeError exception, which necessitates the introduction of the optional chaining operator.
