jco is a JavaScript-focused toolchain for working with WebAssembly Components. It can build a component from a JavaScript or TypeScript module that implements a defined interface, and it can transpile an existing WebAssembly component into a plain ES module so it can be imported and run in Node.js or a browser like ordinary JavaScript.
