What are the 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 used to create objects and encapsulate behavior.

Can you explain how to create a class in JavaScript?

Sure! You can create a class using the class keyword. For example:

class Person {
  constructor(name) {
    this.name = name;
  }
  greet() {
    console.log(`Hello, my name is ${this.name}`);
  }
}

How do I create an object using a function?

You can create an object using a function by defining a constructor function. For example:

function Person(name) {
  this.name = name;
}
const person1 = new Person('Alice');

Which one is better to use, classes or functions?

It depends on your use case. Classes provide a clearer structure and are easier to understand for object-oriented programming, while functions can be more flexible and lightweight.
