## Highlights
- **simplicity:** pretty simple and stable codebase, built on [kind-of][] and [kind-of-extra][]
- **flexibility:** expose methods for each javascript type, using [kind-of-types][]
- **better coverage:** ensures that your code will not have many branches
- **clean stack traces:** clean and small stack traces, using [clean-stacktrace][]
- **type checking:** exposes [is-kindof][] methods for returning booleans
- **negations:** support "not" modifier, e.g. `is.not.array(val)`
- **errors:** enhanced error objects with `actual`, `expected`, `operator` and `value` props
- **messages:** customizable and clean error messages

## API

### [.is](index.js#L139)
> All methods from [is-kindof][] are also exposed, so check its docs. That `.is` is object with methods with same names as in this package.

**Example**

```js
var assertKindof = require('assert-kindof')

assertKindof.is.array(123) // => false
assertKindof.is.array([11, 22, 33]) // => true

assertKindof.array([11, 22, 33]) // => not throws

try {
  assertKindof.array(123) // => AssertionError: number !== array
} catch (err) {
  console.log(err.message) // => 'number !== array'
}
```

### [.array](index.js#L169)
> Check `value` is array, if not throws AssertionError.

**Params**

* `value` **{any}**: value to be checked    
* `message` **{String|Function}**: error message; if function gets `fn(actual, expected, value)` signature    
* `returns` **{Undefined}**: nothing is returned, throws if not okey  

**Example**

```js
var assert = require('assert-kindof')
assert.array([1, 2, 3]) // => not throws
assert.array(123) // => AssertionError: number !== array

try {
  assert.array({ foo: 'bar' }, 'expect `val` to be {expected}')
} catch (err) {
  console.log(err.message) // => 'expect `val` to be array'

**Params**

* `value` **{any}**: value to be checked    
* `message` **{String|Function}**: error message; if function gets `fn(actual, expected, value)` signature    
* `returns` **{Undefined}**: nothing is returned, throws if not okey  

**Example**

```js
var assert = require('assert-kindof')
assert.weakmap(new WeakSet()) // => not throws

assert.weakset(new WeakMap()) // => AssertionError: weakmap !== weakset
assert.weakset(new Map()) // => AssertionError: map !== weakset
assert.weakset(123) // => AssertionError: number !== weakset

try {
  assert.weakset({ a: 1 }, 'expect `val` to be {expected}')
} catch (err) {
  console.log(err.message) // => 'expect `val` to be weakset'
  console.log(err.actual) // => object
  console.log(err.expected) // => weakset
  console.log(err.value) // => { a: 1 }
}
```

## Contributing
Pull requests and stars are always welcome. For bugs and feature requests, [please create an issue](https://github.com/tunnckoCore/assert-kindof/issues/new).  
Please read the [contributing guidelines](CONTRIBUTING.md) for advice on opening issues, pull requests, and coding standards.  
If you need some help and can spent some cash, feel free to [contact me at CodeMentor.io](https://www.codementor.io/tunnckocore?utm_source=github&utm_medium=button&utm_term=tunnckocore&utm_campaign=github) too.

**In short:** If you want to contribute to that project, please follow these things

1. Please DO NOT edit [README.md](README.md), [CHANGELOG.md](CHANGELOG.md) and [.verb.md](.verb.md) files. See ["Building docs"](#building-docs) section.
2. Ensure anything is okey by installing the dependencies and run the tests. See ["Running tests"](#running-tests) section.
3. Always use `npm run commit` to commit changes instead of `git commit`, because it is interactive and user-friendly. It uses [commitizen][] behind the scenes, which follows Conventional Changelog idealogy.
4. Do NOT bump the version in package.json. For that we use `npm run release`, which is [standard-version][] and follows Conventional Changelog idealogy.

Thanks a lot! :)

## Building docs
Documentation and that readme is generated using [verb-generate-readme][], which is a [verb][] generator, so you need to install both of them and then run `verb` command like that

```
$ npm install verbose/verb#dev verb-generate-readme --global && verb
```

_Please don't edit the README directly. Any changes to the readme must be made in [.verb.md](.verb.md)._

## Running tests
Clone repository and run the following in that cloned directory

```
$ npm install && npm test
```
