     1  ## AssemblyScript example
     2  
     3  This example runs a WebAssembly program compiled using AssemblyScript, built
     4  with `npm install && npm run build`.
     5  
     6  AssemblyScript program exports two functions, `hello_world` which executes
     7  simple math, and `goodbye_world`, which throws an error that is logged using
     8  AssemblyScript `abort` built-in function.
     9  
    10  This demo configures AssemblyScript imports for errors and trace messages.
    11  
    12  ```bash
    13  $ go run assemblyscript.go 7
    14  hello_world returned: 10
    15  sad sad world at index.ts:7:3
    16  ```
    17  
    18  Note: [index.ts](testdata/index.ts) avoids use of JavaScript functions that use
    19  I/O, such as [console.log][1]. If your code uses these, compile your code with
    20  the [wasi-shim][2] and configure in wazero using
    21  `wasi_snapshot_preview1.Instantiate`.
