1## AssemblyScript example
2
3This example runs a WebAssembly program compiled using AssemblyScript, built
4with `npm install && npm run build`.
5
6AssemblyScript program exports two functions, `hello_world` which executes
7simple math, and `goodbye_world`, which throws an error that is logged using
8AssemblyScript `abort` built-in function.
9
10This demo configures AssemblyScript imports for errors and trace messages.
11
12```bash
13$ go run assemblyscript.go 7
14hello_world returned: 10
15sad sad world at index.ts:7:3
16```

18Note: [index.ts](testdata/index.ts) avoids use of JavaScript functions that use
19I/O, such as [console.log][1]. If your code uses these, compile your code with
20the [wasi-shim][2] and configure in wazero using
21`wasi_snapshot_preview1.Instantiate`.
