What are the main differences between JavaScript classes and functions?
JavaScript classes are syntactical sugar over JavaScript's existing prototype-based inheritance. Functions, on the other hand, are first-class objects that can be invoked and passed around.
Can you explain how to create a class in JavaScript?
Sure! You can create a class using the class
keyword followed by the class name. For example: class MyClass { constructor() { } }
.
How do I instantiate a class?
You can instantiate a class by using the new
keyword. For example: const myInstance = new MyClass();
.
Are there any advantages to using classes over functions?
Yes, classes provide a clearer structure for creating objects and can make inheritance easier to manage.
