AssemblyScript, as a variant of TypeScript that is syntactically similar to JavaScript, allows developers accustomed to JavaScript to use a familiar language for targeting WebAssembly, potentially reducing the learning curve of a separate language that can be compiled to WebAssembly.

What are the advantages of AssemblyScript?

It offers a large group of developers who already write applications for the web a path to pick up and learn WebAssembly. Even if you are starting from scratch and are not particularly familiar with JavaScript or TypeScript, AssemblyScript is a solid choice when picking a language to start outputting to WebAssembly.

Moreover, the optimized AssemblyScript is almost twice as fast as JavaScript.
