function WebAssembly.instantiate



instantiate(bytes: BufferSource,

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.
