Advanced tools
Package description
The array-differ npm package is a simple utility that allows you to find the difference between two arrays, essentially returning elements that are present in the first array but not in the second. It is useful for filtering out unwanted elements when comparing lists.
Array Difference
This code sample demonstrates how to use array-differ to find the difference between two arrays. It filters out elements from the first array that are not present in the second array, returning [1] in this case.
[1, 2, 3].filter(element => !['2', '3', '4'].includes(element))Lodash provides a method called _.difference which returns the new array of filtered values. It is part of the larger Lodash library which offers a wide range of utilities for working with arrays, objects, and other types. Compared to array-differ, lodash.difference is part of a larger utility library and may be preferred if you are already using Lodash in your project.
Underscore.js is a utility library that offers a function similar to array-differ called _.difference. It works in a similar way but is part of a larger set of utilities that Underscore provides. If you need more than just array difference functionality, Underscore might be a better choice.
Ramda is a functional programming library that includes a difference function similar to array-differ. Ramda's approach is more functional and immutable, which might be preferable for certain coding paradigms. It is a good alternative if you are looking for a library that promotes functional programming.
