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 explain the difference between function declarations and function expressions?

Sure! A function declaration defines a named function and is hoisted, meaning it can be called before it's defined. A function expression, on the other hand, can be anonymous and is not hoisted. For example:

// Function Declaration
function myFunction() {
    // function body
}

// Function Expression
const myFunction = function() {
    // function body
};

What about arrow functions? How do they differ?

Arrow functions provide a more concise syntax for writing functions. They do not have their own this context, which can be useful in certain situations. Here's an example:

const myFunction = () => {
    // function body
};
