Welcome back, my friends.
So in this section, we're going to learn all about JavaScript functions and this is another important
topic that we're going to use for the rest of the course.
So it's going to be a whole lot of fun.
I guarantee you.
In fact, maybe he it's the most important part of JavaScript, so you tell me at the end.
Now, in order to be able to work with JavaScript, we need to understand how functions work precisely.
So functions are the building blocks of everything in JavaScript or OK, almost everything.
So in this section, we're going to focus on functions.
So I'd say pretty much there are three main objectives to this section.
First one will include function declarations and function expressions.
We're going to see where these are and how they're similar, as well as how they're different.
So two ways of writing functions, basically, I want you to be able to write both of them.
Now, the next objective is to explain the difference between console dialogue, something and return
something.
So return is indeed a special word, it's a key word in JavaScript that does a particular special something
and that you're going to see in the section.
Up until this point, we've used console dot log, I think.
Yeah, pretty much always.
But we're going to see the return statement as well.
All right.
And then the third objective is I'd like you to be able to define your own functions, whether their
function declarations or function expressions.
Don't worry, that will become a whole lot clearer once, you know.
Because then we're going to see how to pass arguments to a function.
All right, so this is the video where we sort of outlined and gave an overview perhaps about what we're
going to learn going forward about functions, we can take a break here and continue in the next section.
