# enforce a maximum number of statements allowed in function blocks (max-statements)

The `max-statements` rule allows you to specify the maximum number of statements allowed in a function.

```js
function foo() {
  var bar = 1; // one statement
  var baz = 2; // two statements
  var qux = 3; // three statements
}
```

## Rule Details

This rule enforces a maximum number of statements allowed in function blocks.

## Options

This rule has a number or object option:

* `"max"` (default `10`) enforces a maximum number of statements allows in function blocks

**Deprecated:** The object property `maximum` is deprecated; please use the object property `max` instead.

This rule has an object option:

* `"ignoreTopLevelFunctions": true` ignores top-level functions

### max

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

```js
/*eslint max-statements: ["error", 10]*/
/*eslint-env es6*/

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

  var foo11 = 11; // Too many.
}

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

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

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

```js
/*eslint max-statements: ["error", 10]*/
/*eslint-env es6*/

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

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

    return 42;
  };
}

let foo = () => {
  var foo1 = 1;
  var foo2 = 2;
  var foo3 = 3;
  var foo4 = 4;
  var foo5 = 5;
  var foo6 = 6;
  var foo7 = 7;
  var foo8 = 8;
  var foo9 = 9;
  var foo10 = 10;
  return function () {

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

    return 42;
  };
}
```

### ignoreTopLevelFunctions

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

```js
/*eslint max-statements: ["error", 10, { "ignoreTopLevelFunctions": true }]*/

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