Wrong usage of built-in trace. Plaese see docs
| trace: function (offset, length) { | ||
| var bytes = new Uint8Array(sharedMemory.buffer, offset, length*2); | ||
| globalOffset = offset; | ||
| var string = new TextDecoder('utf8').decode(bytes); | ||

AS uses UTF16-LE. Instead of all of this better to use --bindgen esm which already included proper trace and other bindings. See docs

sorry, I will use a customer function instead of builtin trace

Thanks for efforts! But this example is very basic and doesn't show how to use multithreading with the shared memory from AssemblyScript side. In addition, it contains a lot of mistakes. In general, multithreading on AS isn't yet ready for, because the memory manager is not thread safe, and mutable shared globals should be stored in linear shared memory (at least for "atomic" globals). For now all globals stored as thread local global variables by default. So closing this for now |

I created a simple demo for AS Shared memory with Nodejs, please kindly verify if it is suitable to show this demo.
If it is not suitable, please feel free to decline this PR.
