In this course section,
we are going to leave the world of saving data or files.
I mean, we will, technically, still save data and files
but we'll not dive into different storage techniques
or anything like this.
Instead, in this course section,
we're going to take a closer look at the HTTP requests
that are sent to the server to do something.
Because we're going to dive into Ajax
and JavaScript-driven HTTP requests.
And this very likely sounds extremely cryptic,
and it's not clear what I mean by that.
And therefore, of course, in this course section,
we are going to explore what exactly Ajax
and sending HTTP requests with JavaScript means
and why we might need these features.
And of course, we're not going to stop at the what and why,
but instead in this course section,
like in every other course section as well I guess,
you are also going to learn how to use this feature.
And we're going to learn
how we can send JavaScript-driven HTTP requests,
how we can send our own requests with our own data
once we know why we might want to do that.
And we're of course also going to explore how we can then
handle responses that are being sent back from the server
and how we can also handle possible errors
we might be facing.
So, plenty of things to cover.
Let's dive right in and let's understand
what exactly this course section is about.
