All language subtitles for 001 Dart Overview_en

In the last section, we got a quick overview of how this course is organized and we ended up saying

that will first do a deep dive into the language itself and then eventually shift over to studying flutter

before we move on to our first application.

I want to give you a quick overview of DART itself so that you have some more context on the language.

So let's take a look at a diagram that's going to summarize a few important concepts about DART.

So in this diagram, we're going to take a look at four different important features of Dart.

First off, Dart is a object oriented programming language with an object oriented language.

We spend a lot of time thinking about how to model logic in our application.

Using objects in dart, objects are referred to as classes.

If you've never worked with an object oriented programming language before or don't know what the term

class refers to, that's completely OK.

We're going to do a deep dive on object oriented programming inside this course.

Second, DART is a statically typed language similar to C++, C Sharp or Java.

For reference, languages like, say, JavaScript or Ruby are examples of it dynamically typed languages.

We will of course, discuss static typing quite a bit throughout this course.

But for now, just imagine that in DART we have to make sure that any given variable can only contain

data of a single type like, say, an integer or a string.

If you've never worked with a statically typed language before or if you feel a little bit intimidated

by types, I really recommend you not worry one bit.

The type system and DART is extremely flexible for beginners.

Third, Dart has a sea style syntax, so in general, it's going to look very similar to C, C sharp

or JavaScript or even Java, you will probably not be seeing a lot of strange symbols inside your code.

Most of the code that you and I are going to write is going to look quite legible in my personal opinion.

Finally, Dart has multiple runtime environments, that means to say that we can somehow execute dart

code in the browser from our command line or with mobile apps when ran in the browser, Dart first gets

transpired into plain JavaScript code and we will see a good example of this and one of the apps that

we're going to work on later in the course.

When ran from the command line as a stand alone program, Dart is executed in something called the Dart

VM or the Dart Virtual Machine.

Finally, on a mobile device, Dart is first compiled into machine code.

So your mobile device doesn't ever touch a snippet of pure dart.

It works directly with machine code.

OK, so in the section, we got a very high level view on a couple of different aspects of dirt, let's

now continue in the next section and start working on our first tiny little application.
