#no-labels

#Configuration

import { defineConfig, js } from '@rslint/core';

export default defineConfig([
  js.configs.recommended,
  {
    rules: {
      'no-labels': 'error',
    },
  },
]);

#Rule Details

Disallow labeled statements. Labels tend to be used only rarely and are frowned upon as a remedial form of flow control that is more error prone and harder to understand.

This rule aims to eliminate the use of labeled statements in JavaScript and reports whenever a labeled statement is encountered and whenever break or continue are used with a label.

Examples of incorrect code for this rule:

label: while (true) {}

label: while (true) {
  break label;
}

label: while (true) {
  continue label;
}

Examples of correct code for this rule:

var f = { label: foo() };

while (true) {}

while (true) {
  break;
}

while (true) {
  continue;
}

#Options

• allowLoop (boolean, default false): When true, allows labels attached to loop statements.
• allowSwitch (boolean, default false): When true, allows labels attached to switch statements.

Examples of correct code with { "allowLoop": true }:

A: while (a) {
  break A;
}

A: do {
  if (b) {
    break A;
  }
} while (a);

A: for (var a in obj) {
  for (;;) {
    switch (a) {
      case 0:
        continue A;
    }
  }
}

Examples of correct code with { "allowSwitch": true }:

A: switch (a) {
  case 0:
    break A;
}
