More Ways to Write Functions

You're familiar with function declarations. You define a function using the function keyword. Here's an example:

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

But you can also write the same function like this:

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

In the second case, you're creating an anonymous function -- a function without a name -- and then assigning it to a variable. The variable gives the function a name. This way of defining a function is called a function expression.

With one exception, they'll act the same way. Whether you used a function declaration or a function expression, you'd call your add function like so:

add(1, 2); // 3

You try. Write a function expression that will return the result of multiplying two numbers.
