A recent survey has revealed that Rust has emerged as the most popular language for developing WebAssembly (Wasm) applications. According to the State of WebAssembly 2022 report published by Scott Logic, 45% of surveyed developers reported using Rust for Wasm development, either frequently or sometimes. This marks a significant trend in the growth of Rust’s popularity, as it also topped the rankings in last year’s survey, further solidifying its position as the leading language in this space.
Rust’s Stronghold in WebAssembly Development
Rust’s dominance in the WebAssembly landscape can be attributed to its close integration with Wasm. Many Wasm runtimes are written in Rust, which has made it a natural choice for developers looking to leverage the performance benefits of WebAssembly. The report highlights the advantages Rust brings, such as memory safety and high performance, both of which are crucial when building efficient, low-level WebAssembly applications.
JavaScript and Other Contenders
Coming in second place in the survey was JavaScript, which remains a widely used language in the Wasm ecosystem. JavaScript can be compiled into Wasm, allowing developers to use it in environments where direct support for JavaScript may not be available. However, despite its strong presence, JavaScript has some performance limitations compared to Rust when used in Wasm development, which may explain why Rust continues to lead.
Emerging and Declining Languages
The survey also noted the rise of other languages like Blazor (based on .NET) and Python, which are gaining traction for Wasm applications. On the other hand, AssemblyScript, a language that compiles to WebAssembly and was once a contender, saw a significant decrease in usage. This shift indicates changing preferences within the developer community and a growing demand for languages that provide better integration, safety, and performance for WebAssembly applications.
Overall, Rust’s strong showing in the survey underscores its continued growth in the WebAssembly space, driven by its performance, safety features, and growing developer ecosystem
