utils

Utility functions for all environments. This replaces the underscore dependency.

• utils
  • static
    • .uniq(array, [iteratee]) ⇒ Array
    • .isDate(d) ⇒ boolean
    • .isRegExp(re) ⇒ boolean
  • inner
    • ~isObject(arg) ⇒ boolean

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](https://underscorejs.org/#uniq).

Kind: static method of utils
Params

• 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](https://underscorejs.org/#isDate).

Kind: static method of utils
Params

• d *

utils.isRegExp(re) ⇒ boolean

Returns true if re is a RegExp.

Heavily inspired by [https://underscorejs.org/#isRegExp](https://underscorejs.org/#isRegExp).

Kind: static method of utils
Params

• 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](https://underscorejs.org/#isObject).

Kind: inner method of utils
Params

• arg *
