What is the syntax for defining a function in JavaScript?

In JavaScript, you can define a function using the 'function' keyword followed by the function name, parentheses, and curly braces. For example:

function myFunction() {
    // function body
}

Can you show me an example of a function that takes parameters?

Sure! Here's an example of a function that takes two parameters and returns their sum:

function add(a, b) {
    return a + b;
}

What about arrow functions? How do they differ?

Arrow functions provide a more concise syntax. Here's how you can define the same 'add' function using an arrow function:

const add = (a, b) => a + b;
