The lodash zip() function normally accepts two or more arrays as arguments. Can it accept an array of arrays?
For example, given an object like var aa = [[1,2,3],[4,5,6]]; and a desired output of [[1,4],[2,5],[3,6]] zip() must be called like _.zip(aa[0],aa[1]). For an array of arrays with more than two elements, typing the indexes into the function call becomes repetitive.
Calling _.zip(aa) doesn't work. It just nests the original array of arrays.

If both arrays are in the correct order; where each item corresponds to its associated member identifier then you can simply use. var merge = _. merge(arr1, arr2);
How do you compare objects in Lodash? In Lodash, we can deeply compare two objects using the _. isEqual() method. This method will compare both values to determine if they are equivalent.
The _. sortBy() method creates an array of elements which is sorted in ascending order by the results of running each element in a collection through each iteratee. And also this method performs a stable sort which means it preserves the original sort order of equal elements.
last() method is used to get the last element of the array i.e. (n-1)th element. Parameters: This function accepts single parameter i.e. the array. Return Value: It returns the last element of the array.
You can splat your array of arrays using apply or the ES2015 spread operator (...):
// call zip with a `this` context of the lodash object
// and with each entry in aa as a separate argument
// e. g. zip(aa[0], aa[1], ..., aa[N]);
_.zip.apply(_, aa);
// Same call, but using ES2015
_.zip(...aa)
