### What it does

Disallow labeled statements.

### Why is this bad?

Labeled statements in JavaScript are used in conjunction with `break` and `continue` to control flow around multiple loops. For example:

```js
outer: while (true) {
  while (true) {
    break outer;
  }
}
```

The `break outer` statement ensures that this code will not result in an infinite loop because control is returned to the next statement after the `outer` label was applied. If this statement was changed to be just `break`, control would flow back to the outer `while` statement and an infinite loop would result.
While convenient in some cases, labels tend to be used only rarely and are frowned upon by some as a remedial form of flow control that is more error prone and harder to understand.

### Examples

Examples of **incorrect** code for this rule:

```js
label: while (true) {
  // ...
}

label: while (true) {
  break label;
}

label: while (true) {
  continue label;
}

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

label: {
  break label;
}

label: if (a) {
  break label;
}
```

Examples of **correct** code for this rule:

```js
var f = {
  label: "foo",
};

while (true) {
  break;
}

while (true) {
  continue;
}
```

## Configuration

This rule accepts a configuration object with the following properties:

### allowLoop

type: `boolean`

default: `false`

If set to `true`, this rule ignores labels which are sticking to loop statements.
Examples of **correct** code with this option set to `true`:

```js
label: while (true) {
  break label;
}
```

### allowSwitch

type: `boolean`

default: `false`

If set to `true`, this rule ignores labels which are sticking to switch statements.
Examples of **correct** code with this option set to `true`:

```js
label: switch (a) {
  case 0:
    break label;
}
```

## How to use

To **enable** this rule using the config file or in the CLI, you can use:

::: code-group

```json [Config (.oxlintrc.json)]
{
  "rules": {
    "no-labels": "error"
  }
}
```

```bash [CLI]
oxlint --deny no-labels
```
