Which of the following is NOT a valid use case for arrow functions in JavaScript?
As an event handler function.
As a constructor function.
As a method within an object.
As a callback function in the map method.
Correct: B
Arrow functions cannot be used as constructor functions. They lack the ability to create and initialize objects using the new keyword, and they do not have their own this context. Constructor functions are typically defined using regular functions. However, arrow functions are commonly used in other scenarios like callback functions, event handlers, or when a shorter function syntax is desired.
