How does it work in JavaScript?

Can you explain how functions work in JavaScript?

Sure! In JavaScript, functions are blocks of code designed to perform a particular task. They can be defined using the function keyword.

What are the different ways to define a function?

There are several ways to define functions in JavaScript: function declarations, function expressions, and arrow functions.

What is the difference between a function declaration and a function expression?

A function declaration defines a named function that can be called before it's defined, while a function expression creates a function that can only be called after it's defined.

Can you give me an example of an arrow function?

Absolutely! An arrow function looks like this: const add = (a, b) => a + b;. It's a concise way to write functions.
