/**
|
|
* This method is like `reduce` except that it iterates over elements of
|
|
* `collection` from right to left.
|
|
*
|
|
* @since 0.1.0
|
|
* @category Collection
|
|
* @param {Array|Object} collection The collection to iterate over.
|
|
* @param {Function} iteratee The function invoked per iteration.
|
|
* @param {*} [accumulator] The initial value.
|
|
* @returns {*} Returns the accumulated value.
|
|
* @see reduce
|
|
* @example
|
|
*
|
|
* const array = [[0, 1], [2, 3], [4, 5]]
|
|
*
|
|
* reduceRight(array, (flattened, other) => flattened.concat(other), [])
|
|
* // => [4, 5, 2, 3, 0, 1]
