+[![Actions Status](https://github.com/AssemblyScript/assemblyscript/workflows/CI/badge.svg)](https://github.com/AssemblyScript/assemblyscript/actions)
 
 **AssemblyScript** compiles a strict subset of [TypeScript](http://www.typescriptlang.org) (basically JavaScript with types) to [WebAssembly](http://webassembly.org) using [Binaryen](https://github.com/WebAssembly/binaryen). It generates lean and mean WebAssembly modules while being just an `npm install` away.
