Difference Between Dart and Javascript


For cross-platform mobile app development, JavaScript and Dart are the best solutions. Dart is a newer language but has many useful features and good Google support. JavaScript was at the pinnacle of popularity for cross-platform mobile application and server-side application development. Dart shares the same syntax and coding style as Java, making it simple for developers and coders with OOPS experience. JavaScript is also a reliable, open-source language with a wide range of libraries and frameworks found online.
In comparison to Javascript, the network is relatively modest. Although Dart has excellent libraries and documentation, many programmers are unsure how to utilize it. JavaScript is a lightweight, simple-to-understand, and speedier programming language that is simple to learn for application players. It boosts developer productivity by offering a variety of Javascript libraries and packages.


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.
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 StackOverflow.
Because of its popularity, the JS ecosystem is massive and now, with the advent of cloud component hubs, it even dominates the reusable components “market”. Front-end developers will want to see an alternative to that.
On the other hand, Dart is becoming popular, but it is nowhere near JavaScript. Before Google announced Flutter, Dart was nowhere to be found. Dart has attracted developers who were not in favor of JavaScript. Presently, Dart almost has 45K+ questions tagged on StackOverflow.

What is Dart?

Dart is a client-oriented programming language created by Google in 2011 and is designed to make fast applications for any platform. Google started it as an internal programming language for developing web, server, and mobile apps. Dart compiles source code the same way like C, JavaScript, Java, and C# do. It also has its virtual machine (VM) called Dart VM, utilized to run the native program. It also includes its package management, Pub. After Google announced Flutter for cross- platform mobile app development, it grew popular. The main reason for this is that Flutter is entirely dedicated to Dart.

What is JavaScript?

JavaScript is a web page rendering language.On the other hand, JavaScript later extended its reach to include server-side, non-browser, and mobile application development. JavaScript supports both OOPS and functional programming. Because it’s dynamic, it doesn’t necessitate client-side compilation. NPM is package management for JavaScript. When Facebook released the React and React Native frameworks for web and mobile app development, JavaScript quickly became the most popular programming language. Nonetheless, developers have conflicting feelings regarding JavaScript.

Dart Vs Javascript: Main Features

Main features of Dart

Fully object-oriented: This language, like JavaScript, is based on objects, and if you prefer OOPs concepts, you’ll adore Dart.
Interfaces, mixins, abstract classes, and static typing are among the features it offers.
Easy to learn: Dart is simple to understand and features a syntax similar to C and JavaScript. Because Dart has a lower learning curve, you only need to master a few of its principles before developing your first project.
Portability: Dart can operate on any operating system, and there are no unique hardware or architecture requirements to run this language. Most major mobile operating systems can run Dart- written applications smoothly, while web applications can work in any browser.
Great Productivity: A good programming language can complete many complex jobs in a short period with minimal effort, and Dart excels in this area above most other languages. Everything about it, from its syntax to the work environment behind the scenes, is designed to boost developer efficiency. If you run into something the language can’t handle on its own, it offers an extensive library and package repository on its platform.
One language, many platforms: Dart can manage multiple platforms on his own, including mobile apps, online apps, a desktop app, scripting tasks, and server-side/client-side work. Of course, you just have to write once, and it will run well on a variety of platforms.

Main features of Javascript

Browser Support: All browsers support JavaScript as a scripting language and have built-in support.
Functional Programming Language: Functions can be assigned to variables in Javascript, just like any other data type. Not only that, but a function can take another function as an argument, return a function, and have functions that have no name.
Can be used on both client and server-side: JavaScript has access to the browser’s Document Object Model (DOM), allowing it to alter web pages’ structure in runtime. As a result, javascript may create various effects on websites. In addition, javascript could be utilized on the server-side.
Object-oriented Programming: Although Javascript is an object-oriented language, it differs from other object-oriented programming languages handling objects and inheritance. As a result, javascript can accommodate the majority of object-oriented principles while remaining straightforward to learn and implement.

Integration tools for Dart

•Flutter is Google’s cross-platform mobile UI framework.
•Aqueduct is a server-side framework with multiple threads.
•Dart Web dev is a framework for creating web apps that integrate Google’s services.
•Angular Dart is another popular Dart Web dev alternative.

Integration tools for JavaScript

•Auth0 is a sign-up tool for your apps or APIs that uses tokens.
•Yarn is a package manager that is a good substitute for NPM.
•Gatsby JS is an open-source framework for building speedier React JS websites and apps.

•The parcelis a web application bundler that works quickly.
•ESLint is a well-known JavaScript linter.
•Algolia is a search engine API that allows you to construct your search results.
•Lodash is a library that supports typical programming tasks with utility functions.
•Jetpack wraps webpack to provide a more pleasant development experience.
•CircleCI is a well-known continuous delivery and integration platform.
•Azure Cosmos DB is the globally distributed database service from Microsoft.


When it comes to JavaScript vs Dart, both are great choices for developing cross-platform mobile apps as they are being used in React Native and Flutter respectively. JavaScript is going strong for both web and backend. Although Dart is relatively new in comparison with JavaScript, it wins a race with some cool features and backing from Google. However, JavaScript is also gearing up to get better with newer updates. Hence, the competition between these two languages will go a long way.
