> Check if a string is a regular expression

* The string *must* include the opening & closing forward slash (`/`).

* Regular expression flags, e.g. `gim`, may be optionally included.

## Install

```

$ npm install is-regexp-string

```

## Usage

```js

const isRegexpString = require('is-regexp-string');

// The forward slashes of the regular expression are *required*

isRegexpString('/(foo|bar)/gi');

//=> true

isRegexpString('foo|bar');

//=> false

// Valid RegExp, but matches everything

isRegexpString('/foo|/');

//=> true

```
