Hello, and
welcome to this TypeScript Basics course.
0:09
If you want to improve your skills as a
web developer and increase your chances of
0:13
getting hired, or even promoted,
then you're in the right place.
0:18
TypeScript is being used more and
more in web-based products, for
0:22
good reasons that I'll
talk about in this course.
0:26
But before we continue,
let me talk a bit about myself.
0:30
I'm a full stack developer
based in the UK,
0:35
as you could probably guess by the accent.
0:38
I've been using TypeScript
professionally for about six years, and
0:41
teaching it on and off on platforms like
Udemy and YouTube for about four years.
0:45
So you're in good hands.
0:50
Let's talk about what you're
going to learn in this course.
0:52
This is a basics course.
0:56
So we'll first talk about
what TypeScript is and
0:57
why you should use it
over regular JavaScript.
1:01
Then for the rest of this
course we'll talk about types.
1:04
Types are a huge part of TypeScript.
1:08
We'll talk about what types are, how to
create them, and how to manipulate them.
1:10
By the end of this course,
1:15
you should have a pretty good
understanding of how TypeScript works.
1:17
But you'll also become
a better programmer,
1:22
one who writes code with less errors and
less bugs, all because of types.
1:25
To get the most out of this course,
1:31
there are three things you need to be
comfortable with before getting started.
1:32
The first thing is JavaScript.
1:37
Since TypeScript has everything
that JavaScript has,
1:40
we'll essentially be writing
JavaScript with types.
1:43
So it makes sense to know the basics of
JavaScript before starting this course.
1:47
The next thing you'll need to
know is the commands prompt.
1:53
We won't do anything too complex.
1:56
Just navigate through some directories and
compile some code.
1:58
It's a lot simpler than it
actually sounds, trust me.
2:02
Finally, you'll need to be
comfortable in using a text editor or
2:06
integrated development environment,
IDE for short.
2:10
You don't have to be an expert
with your tool of choice.
2:15
Just be comfortable creating a few files,
writing some code, of course, and
2:18
running some scripts.
2:23
If I've mentioned anything that you
think you need to learn, don't worry,
2:24
there's some links below that should
guide you in the right direction.
2:28
Okay, now that we've got
the requirements out of the way,
2:33
let's start learning some TypeScript.
