instance
{WebAssembly.Instance}
Attempt to initialize instance
as a WASI reactor by invoking its
_initialize()
export, if it is present. If instance
contains a _start()
export, then an exception is thrown.
initialize()
requires that instance
exports a [WebAssembly.Memory
][] named
memory
. If instance
does not have a memory
export an exception is thrown.
If initialize()
is called more than once, an exception is thrown.
