eslint/no-unreachable-loop Nursery

Disallow loops whose body allows only one iteration.

A loop that always exits before a second iteration is usually accidental and can be replaced with simpler control flow.

Examples of incorrect code for this rule:

for (const item of items) {
  console.log(item);
  break;
}

Examples of correct code for this rule:

for (const item of items) {
