Refactor of confusing code - return early pattern

Refactor.js

function returnStuff(argument1, argument2) {
  if (!argument1.isValid()) {
    throw new Exception();
  }

  if (!argument2.isValid()) {
    throw new Exception();
  }

  const otherVal1 = doSomeStuff(argument1, argument2);

  if (!otherVal1.isValid()) {
    throw new Exception();
  }

  const otherVal2 = doAnotherStuff(otherVal1);

  if (!otherVal2.isValid()) {
    throw new Exception();
  }

  return "Stuff";
}
