What is the difference between a function and a class in JavaScript?

In JavaScript, a function is a block of code designed to perform a particular task, while a class is a blueprint for creating objects with shared properties and methods.

Can you give me an example of each?

Sure! A function can be defined like this: function greet() { return 'Hello!'; }. A class can be defined like this: class Person { constructor(name) { this.name = name; } }.

When should I use a function instead of a class?

Use a function for simple tasks or operations that don't require object-oriented features. Use a class when you need to create multiple objects with shared behavior.
