You should have two compiled Wasm files in the /src/assets folder of your project: main.wasm and memory.wasm. Since we need to utilize the malloc() and free() functions exported from memory.wasm in the main.wasm code, our loading code is going to look different from the earlier examples.

/** * Returns an array of compiled (not instantiated!) Wasm modules. * We need the main.wasm file we created, as well as the memory.wasm file * that allows us to use C functions like malloc() and free(). */const fetchAndCompileModules = () =>  Promise.all( ['../assets/main.wasm', '../assets/memory.wasm'].map(fileName ...
