A return; statement with nothing after it is redundant, and has no effect on the runtime behavior of a function. This can be confusing, so it's better to disallow these redundant statements.

Bad Practice

function foo() { return; }

function foo() {
  doSomething();
  return;
}

function foo() {
  if (condition) {
    bar();
    return;
  } else {
    baz();
  }
}

function foo() {
  switch (bar) {
    case 1:
      doSomething();
    default:
      doSomethingElse();
      return;
  }
}

Recommended

function foo() { return 5; }

function foo() {
  return doSomething();
}

function foo() {
  if (condition) {
    bar();
    return;
  } else {
    baz();
  }
  qux();
}

function foo() {
  switch (bar) {
    case 1:
      doSomething();
      return;
    default:
      doSomethingElse();
  }
}

function foo() {
  for (const foo of bar) {
    return;
  }
}
