What are some examples of functions in JavaScript?

Can you give me some examples of functions in JavaScript?

Sure! In JavaScript, functions are blocks of code designed to perform a particular task. For example, a simple function to add two numbers could look like this:

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

You can call this function with two numbers to get their sum.

What about arrow functions? Can you show me an example?

Absolutely! Arrow functions are a more concise way to write functions in JavaScript. Here's an example of an arrow function that adds two numbers:

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

You can use it in the same way as the regular function.

Are there any built-in functions I should know about?

Yes, JavaScript has many built-in functions. For instance, Math.max() returns the largest of the given numbers:

Math.max(1, 2, 3); // returns 3

Can you explain higher-order functions?

Sure! Higher-order functions are functions that can take other functions as arguments or return them. For example:

function greet(fn) {
    console.log('Hello!');
    fn();
}

greet(() => console.log('Nice to meet you!'));
