is-supported-regexp-flag

> Check whether a RegExp flag is supported

Install

``
$ npm install is-supported-regexp-flag
`

Usage

`js
import isSupportedRegexpFlag from 'is-supported-regexp-flag';

isSupportedRegexpFlag('g'); // As in /foo/g
//=> true

isSupportedRegexpFlag('u');
//=> false
`

The RegExp` constructor throws if you're trying to use unsupported flags. This is a nicer way to check for support.
