In this article, we will read about Dart Vs JavaScript, two widely known languages in cross-platform mobile application development. Apart from comparing them, we’ll also study their history, level of popularity, features, advantages & disadvantages. To help you decide which platform is best, we’ll take some key parameters so that you can analyze the performance level and features of both of these platforms. So without wasting further time, let’s start this article.
Dart is a client-driven programming language for fast app development across all platforms. The aim is to provide the most efficient programming language for cross-platform development combined with a scalable execution runtime for designing apps. A language’s technical foundation is defined by the decisions made during development. These decisions define the language’s capabilities and strengths.
Dart is built for a specific technical envelope that’s best suited for client development. Thus they prioritize high-quality production accessible on the web, mobile, & desktop. It is also the basis for Flutter. While it is the language and runtime that powers Flutter applications, it also supports many of the core developer jobs such as formatting, analysis, and testing.
Dart was first introduced in October 2010 at a conference held in Denmark. It was developed by a Danish Programmer named Lars Bark and Kasper Lund, a software engineer. Since Dart could be turned into JavaScript, it was sought after for its cross-browser availability. As a result, Ecma International gave strong approval to its first edition. Subsequently, Ecma International has again accepted the second version of the Dart standard in December 2014. So far Dart has progressed massively with compiling positively with mobile, desktop, and other programming languages including Javascript.
JavaScript is a popular programming language, and it is mostly used for web development. Because it makes web pages more interactive and dynamic, it’s a necessary tool for developing contemporary online apps. They are used primarily for providing web-development services to the clients but they can also be employed on the server-side using technologies like Node.js.
It allows developers to create web page content, manipulate them, respond to user actions, and communicate with servers. JavaScript code can be written directly within HTML documents using <script> tags or as separate external files with a .js extension. You can use JavaScript for creating dynamic and creative websites, building web and mobile apps, writing server-side codes, and developing video games.
JavaScript was created in 1995 by Brendan Eich for Netscape Navigator, the influential web browser at that time. It helped developers create visual elements on the screen for better user interaction bringing dynamic results to their websites. Over the course of the first six months, JavaScript underwent many name changes. Before being dubbed JavaScript, it was first known as Mocha, then LiveScript.
These days, JavaScript is much more than just a web scripting language. JavaScript is a powerful and flexible language that can be utilized in many different contexts. As such, it may be used for imperative programming, more object-oriented styles, functional approaches, and even event-driven models.
Static type checking is a type safety feature of the Dart programming language, which guarantees that the value of a variable always corresponds to its static type. This is also known as sound typing at times. Type annotations are optional despite types being required due to type inference.
Additionally adaptable, the Dart typing system permits the usage of a dynamic type in conjunction with runtime checks, which might be helpful for code that has to be particularly dynamic or for experimentation.Dart has sound null safety integrated into it. Thus, unless you explicitly state otherwise, values cannot be null.
Static code analysis with good null safety allows Dart to shield you against null exceptions at runtime. When Dart finds that a variable is non-nullable, it can never be null, in contrast to many other null-safe languages. Sound null safety results from the retention of non-nullability during runtime, as can be seen when you examine your code while it’s running in the debugger.
Dart has a huge set of core languages to choose from. All Dart programs come with built-in types, collections, and other essential features. With more complex collection types which include binary trees, hashmaps, linked lists, and queues. Performs functions and constants in mathematics as well as the creation of random numbers.
Also supports asynchronous programming like Future and Stream Lists, which can handle SIMD numeric types and fixed-sized data effectively. It has additional I/O functionality for non-web applications, such as file, socket, and HTTP
Interfaces for foreign functions to facilitate communication with other programs that display a C-style user interface.
Dart helps you in running codes through various platforms. It has Native Platform with an ahead-of-time (AOT) compiler for creating machine code as well as a Dart virtual machine (VM) with just-in-time (JIT) compilation for apps aimed at desktop and mobile platforms. Web Platform which can compile apps for development or production that are intended for the web. JavaScript is translated from Dart by its web compiler.
It has a multi-platform UI toolkit powered by Dart platform which provides tools and UI libraries to build UI experiences that can run on iOS, macOS, Windows, Linux, and the web.
A Dart runtime is necessary for code execution, regardless of the platform or compilation method. This runtime is responsible for doing some important tasks like managing memories, where Dart’s managed memory architecture, a garbage collector recovers any memory that isn’t in use. It also executes Dart type system and control isolates.
Javascript uses a light-weight scripting language designed in a way which clients can execute easily in their browsers. Since it primarily focuses on web applications, the set of libraries is also geared towards web applications. It can be easily interpreted, enable you to handle events and even generate custom events. Additionally, it is lightweight, case-sensitive, support dynamic typing and functional programming.
JavaScript isn’t translated into byte-code beforehand because it isn’t a compiled language. It does, however, adhere to the Just-In-Time (JIT) Compilation paradigm. In other words, it is transformed to bytecode right before running. Because of this, JS can be lightweight. JavaScript can operate on devices with even lower processing power.
It is highly case-sensitive. Thus accordingly all keywords, variables, function names and other identifiers must follow a consistent capitalization of letters. It’s important to pay attention to the case while writing JavaScript code since capitalization counts. That implies that you probably won’t receive the same results if a code is written with one character in uppercase and another in lowercase.
JavaScript allows Higher Order Functions, which are functions that return another function. Simply said, functions that are treated like first-class citizens by the JavaScript interpreter behave in a manner similar to that of objects or other variables. This means that we can assign a value to a variable, return them via a different function, and pass them into arguments.
As we know, JavaScript is a cross-platform, it can function on any computer, regardless of the operating system being used. Netscape 2.0 and later comes pre-installed with JavaScript. A piece of JavaScript code will provide the same result with the same setting on all platforms because the JavaScript interpreter is a component of Netscape and operates on platforms that support Netscape.
JavaScript utilizes the prototype based inheritance feature rather than the more widely used class inheritance, hence it is a prototype-based scripting language. This means that we declare the object prototype and utilize this object prototype to construct more objects of the same type, rather than establishing classes and deriving objects from them. Because of the way this behavior resembles that of the object factory function, JavaScript code frequently uses this kind of design pattern.
JS is also equipped with some uniquely built features that can be a great resource tool for developers and professional coders. Some of them are : Nullish Coalescing Operator, Logical Nullish Assignments, Styling Console Log, Object Shorthand, Optional Chaining, Defer/Async Loading, etc.
For the majority of developers outside of Google, Dart is still a relatively new language. Despite the fact that Google has worked hard to document the Dart programming language, developers still have difficulty locating answers to certain issues. Once they understand the fundamentals, developers with an OOPS background can readily comprehend and use Dart due to its Java-like syntax and coding style.
Prior to Google announcing Flutter, Dart was nonexistent. But since Flutter was unveiled at Google I/O, Dart has become much more popular among mobile developers as a React Native substitute. Dart was discovered as a substitute programming language by developers who preferred JavaScript. Dart’s popularity increased significantly as major corporations like Google, etc. adopted Flutter, although it still isn’t quite as common as JavaScript.
Although Dart has excellent documentation, the capabilities of the language can be confusing to new or even seasoned developers. Because Dart’s syntax is clear and resembles Java in most cases, developers having experience with Java may pick up on it quickly. Nonetheless, developers might have a difficult time coming up with fixes for Dart’s issues.
Since Dart is not a widely used programming language and there aren’t many online books or courses accessible, learning the language might be a daunting task for beginners. On the other hand, programmers from other OOPS languages can more readily grasp the fundamentals of Dart thanks to Google’s comprehensive documentation of the language on their official website. Though some of its syntax may seem strange at first, developers will quickly become accustomed to working with Dart with a little bit of practice.
Dart can be built in two different methods: in AOT for greater optimization during the release process, and in JIT for faster development. This allows developers to construct programs in many ways. This method has been applied to the production of Flutter apps.
Currently, Dart and Flutter are being utilized to construct the front end of cross-platform mobile applications. Although backend development is not mentioned, Dart can also be utilized for web development.
Both robust and loose prototyping are supported by Dart. The majority of programming problems in Dart can be discovered during compilation because it is a compiled language. Dart is more type-safe than JavaScript in that regard.
You may use Dart for web and mobile development. Alongside the Flutter framework for creating cross-platform mobile apps, Dart gained popularity. Although it is not done often, Dart can also be used to create web applications. For those who would like to give it a try, there are several tutorials and courses available for creating web apps with Dart. Nevertheless, developers are beginning to take notice of Dart as a result of Flutter’s rapid rise in popularity. Additionally, new Dart bundles are being introduced to the market. Ultimately, the success of Flutter will determine Dart’s destiny.
Although lightweight editors like Sublime or VIM can also be used to develop Dart code, the most popular integrated development environments (IDEs) for developing Dart applications, particularly Flutter apps, are Android Studio and IntelliJ IDEA, which both have the Dart plugin.
Since Google created Dart, it is evident that the company uses it internally. However, other major companies, such as Alibaba, have also embraced Flutter and Dart in order to create cross-platform mobile applications. Other notable businesses that employ Dart are Blossom, WorkTrails, Whale, Mobile, and so forth.
Since JavaScript has been in use for a longer period of time, it is a more developed and reliable language. Utilizing JavaScript is quite simple. Because there are a lot of frameworks and libraries available online, developers can quickly construct apps by utilizing pre-existing code. However, you must first have a basic understanding of programming in general before you can grasp the syntax of JavaScript.
JavaScript is currently used everywhere. No gadget on the planet is without JavaScript installed. JavaScript frameworks are widely used by businesses to create mobile and online applications. Because JavaScript can also be used to write backends and server-side apps, an increasing number of developers have become addicted to the language throughout their professional careers.
There are innumerable JavaScript frameworks available, and new ones are released into the market virtually every year. Thousands of JS packages are available online since developers must share and distribute code. The JavaScript programming language is simple for new developers to pick up and utilize; thanks to pre-existing packages and developer experience.
JavaScript increases the productivity of developers because it is a lightweight, fast, and dynamic programming language. Another reason why developers choose JavaScript over other programming languages is the ease with which common problems may be solved online. There are many libraries and frameworks for JavaScript, but they’re not all created equal. Additionally, new JavaScript frameworks are regularly introduced, which means that developers are continuously required to learn new frameworks, reducing their productivity.
Although it’s not easy for non-programmers to learn JavaScript, it can be easily learned if one understands the fundamentals of programming. For developers who want to learn JavaScript, there are a ton of online tutorials and courses available.
JavaScript may feel lighter and faster because it is an interpreted language. Compared to other compiled languages like Java, it is actually faster. But when Dart was compared to JavaScript, it was substantially faster.
Originally, front-end web development using HTML and CSS made use of JavaScript. But now that the Node.js framework has become popular, JavaScript is also frequently utilized for server-side and backend programming.
JavaScript is an interpreted language, so it can enable duck typing as well as dynamic typing. JavaScript is not a type-safe language; the application developer is free to enter any code. Only at runtime may errors in programming be discovered.
Using various frameworks, JavaScript has dominated mobile and web application development. JavaScript used to be a no-brainer when it came to creating online and mobile applications for startups and small companies, thanks to Facebook’s releases of React and React Native. Many JavaScript frameworks, like Angular and vue.js, are still readily available on the market for creating web apps, progressive web apps, and hybrid mobile apps.
For developing JavaScript, there are various excellent IDEs and editors available. Although developers can utilize lightweight editors like VIM, Sublime Text, Emacs, or Atom, JavaScript doesn’t always require a full-fledged IDE. Nevertheless, some IDEs are useful for developing JavaScript applications, such as WebStorm and Visual Studio Code.
Large corporations utilize JavaScript extensively for creating cross-platform mobile apps as well as web applications. Although Facebook was first to develop React and the React Native framework for internal use, many other major corporations employ JavaScript, such as Instagram, Reddit, eBay, Slack, Airbnb, and so on.
If you ask ten developers which language they prefer, they will probably all give you rather different reasons—for example, some may say they enjoy Javascript, while others might say they prefer Dart. Developers’ choice of language will undoubtedly be influenced by the demands of the project as well as their own and their team’s strengths.
