Check whether a RegExp flag is supported

Install

$ npm install is-supported-regexp-flag

Usage

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.
