## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save is-match
```
## Heads up!
See the [release history](#release-history) to learn about breaking changes in the [v1.0.0 release](https://github.com/jonschlinkert/is-match/releases/tag/1.0.0).
## Usage
```js
var isMatch = require('is-match');
```
### Create matchers:
**from a string:**
```js
var isMatch = matcher('a')
isMatch('a');
//=> true
isMatch('b');
//=> false
```
**from a glob pattern:**
```js
var isMatch = matcher('*')
isMatch('a'); //=> true
var isMatch = matcher('!b')
isMatch('a'); //=> true
var isMatch = matcher('!b')
isMatch('b'); //=> false
```
**from an array of glob patterns:**
```js
var isMatch = matcher(['b'])
isMatch('a'); //=> false
var isMatch = matcher(['b', 'a'])
isMatch('a'); //=> true
var isMatch = matcher(['b', 'c', '*'])
isMatch('a'); //=> true
```
**from a regex:**
```js
var isMatch = matcher(/a/);
isMatch('a');
//=> true
isMatch('b');
//=> false
```
**from a function:**
```js
var isMatch = matcher(function (val) {
return val === 'a';
});
isMatch('a');
//=> true
isMatch('b');
//=> false
```
**from an object:**
```js
var isMatch = matcher({a: 'b'});
isMatch({a: 'b'}); //=> true
isMatch({a: 'b', c: 'd'}); //=> false
isMatch({e: 'f', c: 'd'}); //=> false
```
## Release history
### v1.0.0
**Potentially breaking changes**
* prior to 1.0, when an array of globs was passed, `isMatch()` would return true if _any_ of the globs matched. As of 1.0, `isMatch()` only returns true when _all_ globs match.
* now does number comparisons. there are several ways to compare numbers, I'm open to a discussion or changes if necessary.
