Difference between TypeScript and Dart Languages 2023 : Aalpha


Typescript and Dart are both programming languages used to develop software applications. The two languages are used to create more robust and scalable applications and as an alternative to JavaScript, the most commonly and widely used language for web development. Though both languages have some similarities, they have some essential differences that make each unique. Taking TypeScript into consideration it’s an object-oriented programming language developed by the Microsoft team in October 2012 and maintained by the Microsoft team. TypeScript can be used to create both server-side applications and client-side websites.

TypeScript has some advantages based on its ability to develop server-side and client-side applications, open-source for free community use, handle large-scale projects, and being a superset of JavaScript, the most popular programming language.

Dart, on the other hand, is an open-source class-based programming language developed by Google in 2011 for the development of client-side applications for web and mobile applications. In addition, Dart can also be used in the development of server-side and desktop applications. In this article, we are to discuss the difference between the two languages exploring their syntax, popularity, and performance. By understanding these differences, one can make an informed decision about the language for the next project or study specialization.

Some of the critical differences between TypeScript and Dart is as discussed below:

TypeScript being a superset of JavaScript, it is a famous and widely used language with a broad community compared to Dart. This is so since TypeScript has been adopted by major companies and organizations such as Microsoft, Asana, and Airbnb. This resulted or more resources and community support for the language. TypeScript is also used by most commonly and widely used web application frameworks such as React and Angular. Popular IDEs like Visual Studio Code also supports it. Contrary to Dart, mainly used in the development of mobile apps, the Flutter framework is a good option for developing high-performance mobile and web-based applications.

Checking on the maturity of the two languages, TypeScript is considered the most mature language compared to Dart. This is stated based on the community of use, popularity, tooling, interoperability, and adoption by various companies. On tooling, TypeScript has more libraries and tools available such as Typescript-Specific IDEs and Editors.

Analyzing the tooling and libraries of the two giant languages, TypeScript has a more mature set of tools and libraries available for free. Such libraries include TypeScript Language Service, used for TypeScript language checking and code completion; Typescript Definition Manager(TSD), which is a package manager for providing information about TypeScript libraries; Visual Studio Code, Webpack, Angular, React, and TypeScript Compiler for converting TypeScript to JavaScript code which runs in any JavaScript environment. However, Dart also has good tooling and libraries supported by the Google team.

Typescript is a statically typed language meaning its variable is determined at the compile-time resulting in better performance since compilers can make optimization based on the type information. Dart, on the other hand, is a dynamically typed language meaning that the variable is determined during the run time, resulting in a slower performance since the runtime must perform an additional check to determine the type of the variable. In concert, TypeScript is faster compared to Dart language. This feature is critical in choosing an application to use during the application to develop.

Dart as a language underlays a better option for developing real-time and responsive applications. This is due to its support for the reactive programming paradigm, which means reacting to the changes in the data as the changes occur in a non-blocking way that is different from blocking programming. Thought Typescript can also be used in developing reactive applications by using its libraries, such as RxJS though not a reactive programming language.

Typescript is a superset of JavaScript, the most popular programming language. Stating a superset of JavaScript means that all JavaScript code is a TypeScript code, but not all TypeScript code is a JavaScript code. This results from TypeScript having more additional features in terms of its classes and interfaces. This makes TypeScript an efficient language for developers as they can easily switch from JavaScript. Dart has a syntax similar to C#. Its syntax is designed to be more readable and less prone to errors than JavaScript. It’s a standalone language, meaning that Dart, as a programming language, can execute without needing another language, contrary to TypeScript. Dart can run on its virtual machine or transpire to JavaScript on various environments.

Both TypeScript and Dart are designed to be well-scaled, but the two have different approaches. TypeScript is statically typed, making it easier to scale code as organized information can be used to enforce design patterns and prevent common errors. Dart is dynamically typed, making it more flexible than JavaScript. However, this also makes it hard to write scalable codes as there are fewer checks to prevent common errors.

TypeScript provides static type checking, meaning the types of variables in TypeScript must be declared when it is defined. This helps prevent type-related errors and makes code more maintainable. Dart, however, provides type-checking but is optional, meaning developers can choose to use type-checking or not, depending on their preferences or requirements for the project.

In conclusion

TypeScript and Dart are powerful programming languages used to develop scalable, complex web and mobile-based applications. Still, they have different goals and target other use cases. TypeScript is more focused on enhancing JavaScript by advancing its features, but Dart is focused on providing an easy-to-use and expressive language for building mobile and web applications. One choice of language to use may vary according to the skills and needs of the project. TypeScript is most suited for developing large scalable applications that require static type checking and is popular among companies and developers. On the other hand, Dart is well done for small projects that need to be flexible and fast and primarily used by Google for its web applications.
