WebAssembly.instantiate

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.

MDN

function instantiate(bytes: BufferSource, importObject?: Imports): Promise<WebAssemblyInstantiatedSource>;

function instantiate(moduleObject: Module, importObject?: Imports): Promise<Instance>;

instantiate(bytes: BufferSource, importObject?: Imports): Promise<WebAssemblyInstantiatedSource>

The WebAssembly.instantiate() function allows you to compile and instantiate WebAssembly code.
