eslint/no-useless-return Pedantic

🚧 An auto-fix is planned for this rule, but not implemented at this time.

What it does

Disallows redundant return statements.

Why is this bad?

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.

Examples

Examples of incorrect code for this rule:

function foo() {
  return;
}

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

function baz() {
  if (condition) {
    doSomething();
    return;
  }
}

Examples of correct code for this rule:

function foo() {
  return 5;
}

function bar() {
  if (condition) {
    return;
  }
  doSomething();
}

function baz() {
  return doSomething();
}
