After long time I have come with a new topic. In this article I will introduce you to Google’s web programming language, Dart Programming language. I will explain you what is Dart programming language and why you should learn it. There are few things you should know about dart. So let’s learn about this programming language.

What is Dart ?

Dart is a class-based, single-inheritance and pure object-oriented programming language. Actually, Dart is an open source and structured web programming language developed by Google and announced to the public in year 2011, but its stable release came into existence in 2017. Google developed this web programming language just to replace JavaScript.

Dart is object-oriented language with C-style syntax. It is suitable for modern app development and capable of high-performance implementation. Developers use Dart to create high-quality apps for Android, iOS and the web. With features aimed at client-side development. Dart is great fit for both mobile and web apps. Dart is open source and free, developed on GitHub.

If you are developer, who don’t like JavaScript then Dart programming is the best alternative. You can create mobile apps, web apps or command-line scripts with Dart. It is an easy, fast, productive and portable language ever.

This is sample of basic Dart program

// Define a function.

printNum(int aNumber) {

print(‘The number is $aNumber.’); // Print to console. }

// This is where the app starts executing.

 main() {

var number = 42; // Declare and initialize a variable.

printNum(number); // Call a function

Features of Dart Language

 Object Oriented

Dart language expects programmers to use classes. With dart, you have no option but to include classes. It supports mixins, interfaces, abstract classes, static typing and sound type system.

Optionally Typed

Most languages are either typed or not. In Java, every variable must be declared with type, such as int or string. When a variable is typed, you can’t put different type of value into it. If you tried calling a method that doesn’t exist on that type, then compiler will raise an error.

Optionally typed means you don’t need to declare type of variable while writing program. You can leave the type off and compiler won’t do any extra checking. This is clever move that will help you to speedup programming.

Compatible with JavaScript

You can compile your Dart program code to JavaScript and run application in any browser.

Reified Generics

This feature allows you to type the elements of a collection. Let’s take an example, an Array in JavaScript cannot guarantee that the objects it contains are any specific type. But generics allow you to specify that every single item in an Array or any other collection type. Reified generics go an extra step and allow this type safety past the compiler. Type integrity at run-time is preserved.


An interface is a handy Object-Oriented technique. It defines a type without defining functionality. Once you grok interfaces, you will lament the lack of them in other languages.

Why You Should Learn Dart Programming ?

Here are top 5 reasons why any programmer should learn Dart programming language:

  • Easy to Learn

If you don’t want to put your time to learn programming language that will take you ages to understand. Here is where Dart language will help you. It has very short learning curve. You will need very short time to learn and become expert in Dart.

Why does Dart look so simple? The reason behind it is, it supports both loose and strong typing. This makes it easier for anyone to understand.

  • Dart Encourages Productivity

Dart encourages high levels of productivity. Productivity in this context refer to doing more work within short time. This is something that every programmer wishes to achieve.

Another thing that make Dart a productive is its syntax. Dart has a simple and concise syntax. It is powerful enough to perform complex tasks.

Another feature that makes Dart a productive language is the large collection of libraries that are packaged in it. These libraries will save you from coding every functionality from scratch.

  • Dart uses AOT and JIT Compilation

Dart is capable of compiling both Ahead of Time (AOT) and Just in Time (JIT). Although this feature is not available on all the Dart frameworks. There are many advantages with these methods of compiling a program. AOT is suitable for building native mobile apps that will work natively. On other hand, JIT is mainly used during development and testing apps.

While developing app, JIT allows a programmer to see changes instantly. You don’t have to re-compile every time or wait for app to reload. You can see the changes that you have saved without much hassle.

  • Flexible and Portable

It is very flexible language. This means you can run Dart program anywhere without any limitations. Dart apps can run on Android, iOS, windows, MacOS and any other operating system out there. Web application built by Dart can run on any browser. As a developer, the portability and flexibility of programming language matters a lot. Dart is platform independent.

  • Reactive Programming

Dart programming language is ideal for reactive programming. This type of programming language that deals with data streams, are responsible for every change in a program. Dart can support interactive components of an application such as user interface widgets.

The reactive nature of Dart is because of its garbage collector and fast object allocation. Dart also supports asynchronous programming. This is because of its stream objects.

  • Versatility

Dart programming language is for every programmer or developer. Whether you are app developer, web developer or desktop developer, this language will be useful to you. Dart can be used to develop both client-side and server-side application.


I hope this brief discussion of Dart has sparked your interest to learn this programming language. Thanks for reading. Share your opinions in the comment section.
