eslint/no-empty-function Restriction

What it does

Disallows the usages of empty functions

Why is this bad?

Empty functions can reduce readability because readers need to guess whether it’s intentional or not. So writing a clear comment for empty functions is a good practice.

Example

Examples of incorrect code for this rule:

function foo() {}

const bar = () => {};

Examples of correct code for this rule:

function foo() {
  // do nothing
}

function foo() {
  return;
}
const add = (a, b) => a + b;
