# is-supported-regexp-flag [](https://travis-ci.org/sindresorhus/is-supported-regexp-flag)
|
|
|
|
> Check whether a RegExp flag is supported. Mostly useful for `y` and `u`.
|
|
|
|
|
|
## Install
|
|
|
|
```sh
|
|
$ npm install --save is-supported-regexp-flag
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
```js
|
|
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.
