is-supported-regexp-flag 
Check whether a RegExp flag is supported. Mostly useful for
y
andu
.
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.
