# contains

Evaluates whether the defined **value** equals at least one of the elements of the given array. \
If a string is provided instead, it makes sure that **value** is its sub-string. 

```javascript
import contains from 'deep-waters/contains';

// works both with primitives
const isSubstring = contains('pre'); 

isSubstring('pre-something'); // → true
isSubstring('foo'); // → false

// or plain and nested objects
const containsObj = contains({  foo: 'bar', deep: { bar: 'foo' } });

containsObj([1, 2, 3, 'str', {  foo: 'bar', deep: { bar: 'foo' } }]); // → true;
```
