• instance {WebAssembly.Instance}

    Attempt to begin execution of instance as a WASI command by invoking its _start() export. If instance does not contain a _start() export, or if instance contains an _initialize() export, then an exception is thrown.

    start() requires that instance exports a [WebAssembly.Memory][] named memory. If instance does not have a memory export an exception is thrown.

    If start() is called more than once, an exception is thrown.
