WebAssembly.instantiate() function allows you to compile and instantiate WebAssembly code.
This function has two overloads:
The primary overload takes the WebAssembly binary code, in the form of a typed array or ArrayBuffer, and performs both compilation and instantiation in one step. The returned Promise resolves to both a compiled WebAssembly.Module and its first WebAssembly.Instance.
The secondary overload takes an already-compiled WebAssembly.Module and returns a Promise that resolves to an Instance of that Module. This overload is useful if the Module has already been compiled.
WebAssembly.instantiateStreaming() function compiles and instantiates a WebAssembly module
directly from a streamed underlying source. This is the most efficient, optimized way to load wasm code.
