Is Dart based on Java?

Dart language

Dart, the web programming language of the future created by Google.

During the last few years, we have seen how modern web applications have evolved by making asynchronous requests to retrieve information from the server and compose the interface that the user will use.

For all that has been said, this is why we must pay special attention to Dart, the new open-source language developed by Google.

What is Dart, and how did it come about?

Dart is an open-source, structured and flexible, object-oriented, class-based language with simple inheritance and support for interfaces, abstract classes, and optional data typing.

It has come to allow developers to create more complex web applications with more structured maintenance and a much higher performance than what web applications are used to.

Behind its creation are Lars Bak and Kasper Lund, two of the V8 JavaScript engine creators for Google Chrome, so when developing Dart, both performance and efficiency have been taken into account.

Also involved in the creation of Dart is Gilad Bracha, creator of the Newspeak language and co-author of the Java specifications and the development of the second edition of the Java virtual machine.

At the end of 2014, the forecast of Internet users was 3 billion (40% of the world’s population), a figure that has doubled in the last five years. Cloud computing and mobile devices with Internet access have brought massive access to web applications, and to process this huge amount of requests that are received by the servers, it is necessary to download them from all the processes that can be carried out from the client-side. Also, new forms of digital entertainment are gaining ground, such as the use of content in video format or streaming playback.

Dart Vs. Java Script

Dart vs. JavaScript, the two competing programming languages in cross-platform mobile application development. JavaScript reached the height of its popularity when it entered cross-platform mobile application development and server-side development. Since the Node.js framework can be used for both frontend and backend development, JavaScript became highly popular among web developers. With the rise of React Native by Facebook, mobile app developers started to move towards JavaScript. As a result, JavaScript remains the most popular programming language to this day.

As an alternative to JavaScript or React Native, Google created the framework for cross-platform mobile application development. Flutter uses the Dart programming language, which many developers do not know. However, in contrast to React Native apps, apps built with Flutter look slick and much more native.

Does a question then arise as to why Google chose Dart over JavaScript or other programming languages for its mobile SDK? Let’s compare both languages on different criteria or comparison points:

1. Ease Of Use

JavaScript has been around longer in the industry and is a mature and stable language. JavaScript is very easy to use. It has numerous frameworks and libraries available online, so developers can use the existing code for developing apps faster. However, to learn the JavaScript syntax, we need to have a basic technical knowledge of programming in general.

Dart is a fairly new language for most of the developers outside of Google. Although Google has put a lot of effort into documenting the Dart programming language, it’s still hard for developers to find solutions for specific problems. In terms of coding style and syntax, it has Java-like syntax, so developers from OOPS background can master and use Dart easily once they learn the basics.

2. Popularity

JavaScript is everywhere. There is almost no device that does not run JavaScript. Currently, JavaScript is being used to write web, mobile and server-side code. JavaScript has almost 2.5+ million questions tagged on Stack Overflow.

Is Dart similar to Java?

Unlike many languages, Dart was designed to make the development process as comfortable and fast as possible for developers. So it comes with a fairly extensive set of built-in tools, such as its package manager, various compilers/ transpilers and a parser.   Additionally, the Dart virtual machine and Just-in-Time compilation make code changes immediately executable.

Once in production, the code can be compiled into the native language, so there is no need for a special running environment. In the case of web development, Dart is trans piled to JavaScript.

In terms of syntax, Dart is very similar to languages ​​like JavaScript, Java, and C ++, so learning Dart knowing one of these languages ​​takes a matter of hours.

Also, Dart has great support for asynchrony, and working with generators and iterables is extremely easy.

Where can I use Dart?

Dart is a general-purpose language, and you can use it for almost anything:

In web applications, using the art library: HTML and the transpiler to transform the Dart code into JavaScript, or using frameworks like Angular Dart.

On servers, it uses art: HTTP and art: io libraries. Several frameworks can be used, such as Aqueduct.

In console applications.

In mobile applications, thanks to Flutter.

Flutter

Flutter is a Dart framework for creating cross-platform applications with a single code. Unlike other cross-platform frameworks such as Ionic, the code of a Flutter application is compiled to native code. The performance achieved is superior to applications based on web views. Also, unlike React Native, Flutter does not use native components. Still, it comes with its components, called widgets, so that the same application will look the same on any device, regardless of its operating system or version. The developer does not have to worry about their application design looking bad on older devices.

What is Dart used for?

The Dart programming language was developed primarily by Google. Dart is an Ecma standard, the European organization for the standardization of computer and communication systems and electronic products. Dart programming is an interesting alternative to JavaScript in today’s web browsers. According to the Dart developers, it is no longer possible to fix JavaScript’s shortcomings through language development.

Google’s Dart language began development in 2010 and was introduced a year later. As browsers could not, and cannot, work with this language naturally, and JavaScript can run in all current browsers, there is the Dart2js compiler, that is, “Dart for JavaScript.” The Dart language resembles the already established object-oriented programming languages, including Swift, C # or Java, which are subordinated to certain programming paradigms. The rules for combining defined characters, that is, the syntax, are similar to the C language. This similarity greatly facilitates learning so that it is possible to get started without having to face major language problems.

Google Dart is primarily focused on programming Internet-enabled devices, that is, smartphones, tablets, and computers, but also servers. Until recently, the idea of ​​novice programmers developing their mobile or web applications was somewhat unrealistic. The Dart language has the goal of simplifying the programming of such applications. Flutter, Google’s own software development kit, is programmed with Dart, the popular Google Ads advertising tool. Other examples are the websites of the New York Times newspaper or the Groupon service. The DartPadoffers mentioned above the comfortable possibility of approaching the programming language with the trial and error method and thus acquire basic knowledge.

Advantage

Dart is an open-source language and, therefore, free to access for anyone. Behind Dart programming is the giant Google, offering long-term prospects for language development.

Dart script 

Dart was originally introduced to address shortcomings in JavaScript that could no longer be improved within the programming language itself from the developers’ point of view. In this way, they began to find a way to simplify or bring together certain internal logic without renouncing the range of language possibilities. As an example, the JavaScript code would be as shown below:

 getElementsById()

getElementsByTagName()

getElementsByName()

getElementsByClassName()

querySelector()

querySelectorAll()

document.links

document.images

document.forms

document.scripts

formElement.elements

selectElement.options

Instead, in code in Dart it would be like this:

elem.query(‘#foo’);

elem.queryAll(‘.foo’);

First steps to learn Dart

A programming language is made up of many “vocabulary” with which data is structured, and operations (algorithms) are developed. The language uses a certain number of concepts: variables, which only have one purpose. Some examples in Dart are “var”, “int” “if”, “else” or “while”. In our article on Internet programming languages, you will discover more about the architecture of programming languages. By combining variables, operators, conditionals, functions, and many other elements, the program’s sequence is born at the end of which a result is obtained.

Dart in practice

We present you the first examples, simple and easy to understand, to learn Dart. You can modify them to your liking and experiment with them. All programming routines begin with the call to the primary function. As an example, we take the classic “Hello world” code:

void main () {

 print(“Hola, mundo”); 

}

Dart tutorial

First, the first thing we have to consider is the space necessary to practice darts at home. For this, we will need a space of approximately 1m wide and 3m long for the shooting area, regardless of the type of target we have.

Once we are clear on this, the target will be fixed, usually on the wall, although today, different systems offer various options to carry out this task.

Composition of the domestic electronic target.

So with everything, the elements and factors to take into account, depending on the type of target we have, are the following:

Traditional Diana

It is advisable to use a protective surround for the wall or, failing that, to install a panel on the back of the target to avoid damaging it with the darts’ tips that do not find the target during the launches.

It is also especially important to have a protective mat on the ground or a Dart Mat that does the double function of protecting the ground and delimiting both the playing area and indicating the shooting position (shooting line).

· If a Dart Mat is not used, a line of fire is required that indicates the appropriate throw distance. For this, there are two options:

Sticky line of fire: It is located at the launch point.

Laser firing line: It is usually installed below the target and is oriented towards the launch point.

Dart vs. Python

Python’s problem is that Python has unresolved issues like static types, static code declaration, etc. once they created Dart, they made it a priority to form Dart code to be more static than JavaScript was. For example, while in JavaScript, you’ll add, remove methods at runtime, in Dart that wasn’t visiting be supported.

Notice that Guido has been more interested in adding static types to Python, but it’s just something difficult to try to do after numerous} years, which would change Python a lot. Guido, for several years, was reluctant to feature static types, but the pressure kept growing to feature them in Python. If you were to begin a language from scratch, you’d fair an improved chance of getting static types right from the get-go. Dart failed at that when Dart 1.0 was “optionally typed.” The Dart developers want to redeem themselves and have Dart 2.0 have static types that mean it.

Once you create something like Python but has different semantics and maybe syntax, you cannot share the code with Python.

What is Dart? a brand new web programing language with libraries, a virtual machine, and tools. Dart may be a cohesive, scalable platform for building apps that run on the net (where you’ll use Polymer) or on servers (such as Google Cloud Platform). Use the Dart language, libraries, and tools to jot down anything from simple scripts to full-featured apps.

Python is a transparent and powerful object-oriented artificial language, adore Perl, Ruby, Scheme, or Java. Python may be a general-purpose programing language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code; if you’re just beginning your programming career, python suits you best. Python utilizes different technology stack for developing high-quality apps for seamless business and profits. Here is the technology stack used in Python:

• Keras
• Tensorflow
• Django
• Flask
• Pytorch
• Python
• Anaconda

Conclusion

In the battle of Dart Vs. JavaScript, both are the winners as they are solid choices for developers due to various reasons. In a poll done by Jaxenter, Dart was voted the number one language in your 2019 list with 223 votes. Furthermore, Dart(66.3%) was just behind JavaScript(66.8%) as the most loved programming language of 2019 in a survey done by Stack Overflow. Dart was also ranked number one in the fastest growing language category of the “Github State of the October.” JavaScript is trustworthy, but Dart is also reliable for its cool and supportive features for Google. It is very difficult to judge which will dominate the future world as Dart has also started earning the developer’s trust.

As you have seen, Dart already puts at your disposal very good features so that you can start working with it on the client-side, on the server-side, or create command-line applications.

Dart will become the next programming standard for many of us and will revolutionize web development, marking a before and after in the way we structure and develop web applications.

As we have already mentioned for Dart, performance is important. Still, the performance of your applications is also important. You can make adequate measurements and detect possible memory errors. It incorporates a new application called Observatory that allows you to analyze time consumption, losses or fragmentation memory, lines of code executed, and memory allocated.

To complete this cast, Dart has some very interesting extras:

• dartfmt tool to auto-format code so that all projects have a similar structure.
• Dart analyzer that deals with analyzing in real-time the Dart code you write to detect errors at development time. It also shows information and notices of interest so you can be more productive.
• Dozen is in charge of generating all the documentation of your projects from the documentation comments.
