WebAssembly in Action
A browser’s JavaScript engine monitors the code until it’s satisfied it knows the variable types before it can convert that section of JavaScript into machine code.

Because the variable types are all known in advance, when the browser loads the WebAssembly file, the JavaScript engine doesn’t need to monitor the code. It can compile the binary format straight into machine code.
