### utils.uniq(array, [iteratee]) ⇒ Array
Produces a duplicate-free version of the array, using === to test object equality. In particular only the first occurrence of each value is kept. If you want to compute unique items based on a transformation, pass an iteratee function. Heavily inspired by https://underscorejs.org/#uniq
**Kind**: static method of [utils](#module_utils)
| Param | Type | Description |
| --- | --- | --- |
| array | Array | |
| [iteratee] | function | transformation applied to every element before checking for duplicates. This will not transform the items in the result.
| ### utils.isDate(d) ⇒boolean
Returns true if d is a Date. Heavily inspired by https://underscorejs.org/#isDate
**Kind**: static method of [utils](#module_utils)
| Param | Type |
| --- | --- |
| d | \* |
### utils.isRegExp(re) ⇒ boolean
Returns true if re is a RegExp. Heavily inspired by https://underscorejs.org/#isRegExp
**Kind**: static method of [utils](#module_utils)
| Param | Type |
| --- | --- |
| re | \* |
### utils~isObject(arg) ⇒ boolean
Returns true if arg is an Object. Note that JavaScript arrays and functions are objects, while (normal) strings and numbers are not. Heavily inspired by https://underscorejs.org/#isObject
**Kind**: inner method of [utils](#module_utils)
| Param | Type |
| --- | --- |
| arg | \* |
