is-supported-regexp-flag

Check whether a RegExp flag is supported. Mostly useful for y and u.

Install

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

Usage

var isSupportedRegexpFlag = require('is-supported-regexp-flag');

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

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

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