# Require PascalCased class and interface names (class-name-casing)

This rule enforces PascalCased names for classes and interfaces.

## Rule Details

This rule aims to make it easy to differentiate classes from regular variables at a glance.

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

```ts

class invalidClassName {

}

class Another_Invalid_Class_Name {

}

var bar = class invalidName {}

interface someInterface {}

```

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

```ts

class ValidClassName {

}

export default class {

}

var foo = class {};

interface SomeInterface {}

```

## When Not To Use It

You should turn off this rule if you do not care about class name casing, or if
you use a different type of casing.
