Lodash _.pullAll() Method

Lodash _.pullAll() method is used to remove all the values from the first given array that are given in the second array.

_.pullAll(array, values);

array: This parameter holds the array that needs to be modified.
values: This parameter holds the values in an array that need to be removed from the first array.

It returns an array with all the values that are removed from the first array.

Example 1: In this example, it removes the second array of elements from the first array and returns the remaining elements.

javascript

const _ = require('lodash');
 
let ar = [1, 2, 3, 4, 5]
let rem = [1, 3]
let value = _.pullAll(ar, rem)
 
console.log(value)

Output:

[ 2, 4, 5 ]

Example 2: In this example, it removes the second array of elements from the first array and returns the remaining elements.

javascript

const _ = require('lodash');
 
let ar = [1, 2, 3, 1, 3, 4, 1, 5]
let rem = [1, 4, 5]
let value = _.pullAll(ar, rem)
 
console.log(value)

Output:

[ 2, 3, 3 ]

Example 3: In this example, it removes the second array elements from the first array and returns the remaining elements.

javascript

const _ = require('lodash');
 
let ar = ['a', 'b', 'c', 'd']

let rem = ['b', 'c']
let value = _.pullAll(ar, rem)
 
console.log(value)

Output:

[ 'a', 'd' ]

Note: This will not work in normal JavaScript because it requires the library lodash to be installed.
