/**
|
|
* This method is like `uniq` except that it accepts `iteratee` which is
|
|
* invoked for each element in `array` to generate the criterion by which
|
|
* uniqueness is computed. The order of result values is determined by the
|
|
* order they occur in the array. The iteratee is invoked with one argument:
|
|
* (value).
|
|
*
|
|
* @since 4.0.0
|
|
* @category Array
|
|
* @param {Array} array The array to inspect.
|
|
* @param {Function} iteratee The iteratee invoked per element.
|
|
* @returns {Array} Returns the new duplicate free array.
|
|
* @see uniq, uniqWith
|
|
* @example
|
|
*
|
|
* uniqBy([2.1, 1.2, 2.3], Math.floor)
|
|
* // => [2.1, 1.2]
