What will happen when attempting to call freddie.colorChange('orange')?

When calling freddie.colorChange('orange'), a TypeError will occur if 'colorChange' is not defined as a method within the 'freddie' object or if it is not properly set up as a function. In JavaScript, an attempt to call a method that does not exist for an object directly results in an error because JavaScript does not accommodate calls to undefined functions.

If 'freddie' is an instance of an object that lacks the 'colorChange' method, trying to invoke this method will throw a TypeError indicating the method cannot be executed since it does not exist within the 'freddie' scope. This aligns with the nature of JavaScript's dynamic type system where method existence is verified at runtime, and using a method that is not declared will lead to an immediate error.

This understanding is crucial for developers as it emphasizes the importance of checking method definitions and ensuring they are correctly implemented before attempting to call them on an object. Understanding how JavaScript handles object methods and the associated errors enhances the development process and avoids runtime issues.
