### What it does

Enforce a maximum number of statements in a function. This rule ensures
that functions do not exceed a specified statements count, promoting smaller,
more focused functions that are easier to maintain and understand.

### Why is this bad?

Some people consider large functions a code smell. Large functions tend to
do a lot of things and can make it hard to follow what's going on.
This rule can help avoid large functions.

### Examples

Examples of **incorrect** code for this rule with the default `{ "max": 10 }` option:

```js
function foo() {
  const foo1 = 1;
  const foo2 = 2;
  const foo3 = 3;
  const foo4 = 4;
  const foo5 = 5;
  const foo6 = 6;
  const foo7 = 7;
  const foo8 = 8;
  const foo9 = 9;
  const foo10 = 10;

  const foo11 = 11; // Too many.
}

const bar = () => {
  const foo1 = 1;
  const foo2 = 2;
  const foo3 = 3;
  const foo4 = 4;
  const foo5 = 5;
  const foo6 = 6;
  const foo7 = 7;
  const foo8 = 8;
  const foo9 = 9;
  const foo10 = 10;

  const foo11 = 11; // Too many.
};
```

Examples of **correct** code for this rule with the default `{ "max": 10 }` option:

```js
function foo() {
  const foo1 = 1;
  const foo2 = 2;
  const foo3 = 3;
  const foo4 = 4;
  const foo5 = 5;
  const foo6 = 6;
  const foo7 = 7;
  const foo8 = 8;
  const foo9 = 9;
  return function () {
    // 10

    // The number of statements in the inner function does not count toward the
    // statement maximum.

    let bar;
    let baz;
    return 42;
  };
}

const bar = () => {
  const foo1 = 1;
  const foo2 = 2;
  const foo3 = 3;
  const foo4 = 4;
  const foo5 = 5;
  const foo6 = 6;
  const foo7 = 7;
  const foo8 = 8;
  const foo9 = 9;
  return function () {
    // 10

    // The number of statements in the inner function does not count toward the
    // statement maximum.

    let bar;
    let baz;
    return 42;
  };
};
```

Note that this rule does not apply to class static blocks, and that statements in
class static blocks do not count as statements in the enclosing function.

Examples of **correct** code for this rule with `{ "max": 2 }` option:

```js
function foo() {
  let one;
  let two = class {
    static {
      let three;
      let four;
      let five;
      if (six) {
        let seven;
        let eight;
        let nine;
      }
    }
  };
}
```

Examples of additional **correct** code for this rule with the
`{ "max": 10 }, { "ignoreTopLevelFunctions": true }` options:

```js
function foo() {
  const foo1 = 1;
  const foo2 = 2;
  const foo3 = 3;
  const foo4 = 4;
  const foo5 = 5;
  const foo6 = 6;
  const foo7 = 7;
  const foo8 = 8;
  const foo9 = 9;
  const foo10 = 10;
  const foo11 = 11;
}
```

## Configuration

This rule accepts a configuration object with the following properties:

### ignoreTopLevelFunctions

type: `boolean`

default: `false`

Whether to ignore top-level functions.

### max

type: `integer`

default: `10`

Maximum number of statements allowed per function.

## 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": {
    "max-statements": "error"
  }
}
```

```bash [CLI]
oxlint --deny max-statements
```
