Lodash _.pullAll

Overview

The lodash _.pullAll method is a powerful utility function used in JavaScript programming. It is part of the popular lodash library that provides a wide range of helper functions to simplify coding tasks.

The _.pullAll method removes all elements from an array that are also present in another given array. The array is modified in place and the method returns the modified array. If the array doesn't contain the value, it does not modify it.

The method takes two arguments: the first is the array to be modified, and the second is the array of elements to be removed from it. The function is very useful when you want to delete multiple specific items from an array.

Here is an example usage of the _.pullAll method:

const array = ['a', 'b', 'c', 'd'];
_.pullAll(array, ['b', 'd']);
console.log(array);
// Output: [ 'a', 'c' ]

In this example, the _.pullAll method removed the 'b' and 'd' elements from the 'array' and returned the new array, which includes only the remaining elements 'a' and 'c'.

The _.pullAll method is very useful when you have an array of items and you want to remove all items that match a certain set of criteria. It can be used in a wide range of projects, including data processing, filtering, and sorting.

That is a brief overview of the lodash _.pullAll method - a powerful tool for modifying arrays in JavaScript programming.
