Creates an array of elements split into groups the length of size.If array can't be split evenly, the final chunk will be the remaining elements. Otherwise, isEqualWith will pre-check if both objects have the same number of keys and return false before getting to the next loop where it goes through each key. Performs a deep comparison between two values to determine if they are equivalent. Other answers provide potentially satisfactory solutions to this problem, but it is sufficiently difficult and common that it looks like there's a very popular package to help solve this issue deep-object-diff. Details can be found in Changelog. Works like a charm, just that the order of obj1 and obj2 is important.

Performs a deep comparison between two values to determine if they are equivalent. It is a recursive analogue of a previous contribution to this thread. With arrow functions, we can define curried functions explicitly, making them easier to understand for other programmers: These explicitly curried arrow functions are particularly important for debugging: If were using a functional library like lodash/fp or ramda, we can also use arrows to remove the need for the auto-curry style: As with currying, we can use arrow functions to make partial application easy and explicit: Its also possible to use rest parameters with the spread operator to partially apply variadic functions: Lodash comes with a number of functions that reimplement syntactical operators as functions, so that they can be passed to collection methods. isEmpty The isEmpty method checks if value is an empty object, collection, map, or set.
