# funsert [](https://travis-ci.org/floatdrop/funsert)
> Functional assert library
## Install
```
$ npm install --save funsert
```
## Usage
```js
var is = require('funsert');
var aboveFive = is.greaterThan(5);
var belowTen = is.ok(x => x < 10, 'below 10');
var inBounds = is(aboveFive, belowTen);
inBounds(7);
inBounds(3);
//=> Throws '3 is not greater than 5'
```
## API
This is still under heavy development. Happy to hear suggestions before `1.0.0` release!
### funsert(assertions...)
Compose assertions with `and` operation.
### funsert.ok(check, [message])
Runs `check` function and throws Error, if it returns `false`.
### Helpers
Funsert wraps some predicate functions from [predicates](https://github.com/wookieb/predicates):
- array
- equal
- lessThan
- greaterThan
- instanceOf
- hasOwnProperty
- hasProperty
- in
- matches
- strictEqual
- endsWith
- startsWith
