function WebAssembly.instantiate
          
instantiate(bytes: BufferSource,importObject?: Imports,): Promise<WebAssemblyInstantiatedSource> 
      The WebAssembly.instantiate() function allows you to compile and instantiate WebAssembly code.
This 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.

instantiate(): Promise<Instance> 
      The WebAssembly.instantiate() function allows you to compile and instantiate WebAssembly code.
This 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.
