Dart and JavaScript, two of the most competitive programming languages for creating cross-platform mobile applications, will be compared to learn about their advantages, disadvantages, and unique features.
React Native and Flutter are excellent examples of cross-platform mobile app development using Dart vs JavaScript, respectively. Compared to JavaScript, Dart is a relatively young language, but it offers several really useful features and excellent Google support.
It is now quite tough to pick which of the two is better, although Dart is currently doing fantastically well because of how strongly it has taken off.
Dart
Dart began its voyage in 2011, but it did not gain much traction until Google released a stable version of it in 2017. Internally at Google, Dart was first utilised to create web and mobile applications. While the standalone Dart SDK is provided with a Dart VM and has its own package management called a pub, Dart generates the source code similarly to JavaScript.
Main features of Dart
Easy to learn
Dart’s syntax is simple to learn and will make you think about JavaScript and C. Since Dart has a lower learning curve, you only need to properly understand a handful of its fundamentals to construct your first project using it.
Portability
Dart’s syntax is simple to learn and will make you think about JavaScript and C. Since Dart has a lower learning curve, you only need to properly understand a handful of its fundamentals to construct your first project using it.
Great productivity
A good programming language should be able to execute a huge number of challenging jobs quickly and with minimal effort, and this is where Dart stands apart from the majority of other languages.
Javascript
When Facebook introduced the React & React Native frameworks for creating online and mobile applications, JavaScript quickly overtook all other popular languages in popularity. Since JavaScript is dynamic in nature, client-side code compilation is not necessary, and it has its own package managers, such as NPM.
Main features of JavaScript
Browser Support
Every browser supports JavaScript and accepts it as a programming language.
Functional Programming Language
In Javascript, functions may be assigned to variables the same way that any other data type can. A function can also contain functions without names, return another function, and accept another function as a parameter.
Useful for both client-side and server-side
The Document Object Model (DOM) of the browser, which JavaScript has access to, allows you to modify the structure of web pages in real-time. Javascript may therefore be used to provide various effects to websites. Javascript may also be utilised on the server side.

Object-oriented Programming
Even though Javascript is an object-oriented language, it handles inheritance somewhat differently than other traditional object-oriented programming languages like Java. Because of its ease of use and compatibility with the majority of object-oriented ideas, javascript is widely used.
Main Differences between Dart and JavaScript
Ease of Use
Since it has been used in the business for longer, JavaScript is a more developed and reliable language. JavaScript is easy to operate. It has a number of online-accessible frameworks and libraries.
On the other hand, the majority of engineers outside of Google are unfamiliar with Dart. Although Google has made an attempt to document the Dart programming language, it is still challenging for developers to discover precise answers to issues.
Speed
Due to the fact that JavaScript is an interpreted language, it may feel lighter and execute more quickly than other programming languages. It is quicker than compiled languages like Java.
Dart, on the other hand, is a lot quicker than JavaScript. Dart may be JIT and AOT compiled, which aids in the creation of apps in numerous ways.
Type Safety
As an interpreted language that enables dynamic and Duck typing, JavaScript. Because it can type any code, JavaScript is not a type-safe language. Only during runtime may programming flaws be discovered.
Contrarily, Dart encourages both flexible and rigid prototyping. Because Dart is a compiled language, the majority of programming issues are discovered during the compilation stage. It is more type-safe than JavaScript, in my opinion.
Popularity
You can use JavaScript everywhere. JavaScript is almost universally supported on computers. Currently, server-side, web, and mobile codes are all created using JavaScript. There are about 2.5 million questions regarding JavaScript on Stack Overflow.
Dart, on the other hand, is becoming more and more popular yet it cannot compete with JavaScript. Before Google released Flutter, Dart was unheard of. Developers that have previously resisted JavaScript have switched to Dart. Stack Overflow has over 45K queries classified as Dart right now.
Learning Curve
JavaScript is not an easy language for beginners to learn, but once you understand the basics of programming, JavaScript becomes straightforward. Developers who wish to learn JavaScript may find several online tutorials and courses.
On the other hand, because it is not a commonly used programming language, learning the Dart programming language might be difficult for novices. There aren’t many online books or courses for Dart programming.
Final Words
After reading through this thorough comparison of JavaScript vs. Dart, we are unable to pick one technology over the other because they are both equally beneficial and capable.
The main takeaway from this talk is that JavaScript is unquestionably the best language for client-side and server-side programming, and Dart is rapidly gaining ground because it is virtually as flexible and user-friendly as JavaScript. The ability to select the best of both worlds, depending on their project and skill requirements, benefits the development community.
