Dart vs WebAssembly: What are the differences?
Introduction
Dart and WebAssembly are two technologies commonly used in web development. They have some key differences that set them apart from each other. In this article, we will explore six major differences between Dart and WebAssembly.
-
Execution Environment: Dart is a programming language developed by Google that can be run natively on multiple platforms, including web browsers, servers, mobile devices, and IoT devices. On the other hand, WebAssembly is a binary format that is executed in a sandboxed environment within the web browser.
-
Languages: Dart is a high-level, object-oriented language with a syntax similar to Java or JavaScript. It provides a wide range of language features and a comprehensive standard library. WebAssembly, on the other hand, is a low-level language that can be compiled from various source languages such as C, C++, Rust, and others.
-
Performance: Dart programs are executed by the Dart virtual machine (VM) or can be compiled to JavaScript for broader compatibility. The Dart VM provides efficient just-in-time (JIT) compilation, which can optimize code execution at runtime. WebAssembly, on the other hand, is designed to be fast and efficient, providing near-native performance.
-
Portability: Dart can be used to build web applications that run in web browsers, as well as native mobile apps for Android and iOS. It also supports server-side development. WebAssembly, on the other hand, is specifically designed for web browsers but can be used in other contexts via frameworks like Node.js.
-
Tooling and Ecosystem: Dart comes with a comprehensive set of development tools, including an IDE (IntelliJ IDEA, Visual Studio Code), package manager (Pub), and testing frameworks. It also has a growing ecosystem of libraries and frameworks. WebAssembly, being a binary format, requires specific tooling for compilation and optimization. It has a more limited ecosystem compared to Dart.
-
Maturity and Adoption: Dart has been around since 2011 and has gained a significant following, particularly in the Flutter community. It has matured over the years and is used in production by many companies. WebAssembly, on the other hand, is relatively newer and has seen rapid adoption. It is supported by major browser vendors and has gained popularity as a way to run computationally-intensive operations in web applications.
In summary, Dart is a versatile programming language that can be used across multiple platforms, while WebAssembly is a low-level binary format specifically designed for web browsers. Dart provides extensive tooling and a mature ecosystem, while WebAssembly offers near-native performance and broader language compatibility in the web environment.
