AssemblyScript is a programming language designed specifically for WebAssembly, closely resembling TypeScript to facilitate a smooth transition for developers. This language allows for low-level control over code while simplifying the compilation process, making it accessible to developers familiar with TypeScript. Users can easily integrate it into the existing web ecosystem without the need for complex toolchains, simply requiring an npm installation to get started.

The software is free and open-source, adhering to the Apache License, Version 2.0, and is built on the WebAssembly specification with support from Binaryen. AssemblyScript is suitable for a diverse range of users including small businesses, enterprises, freelancers, and nonprofits. The primary support for users comes in the form of comprehensive documentation, ensuring that developers can quickly learn and utilize its features effectively.
