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

let rem = [1, 4, 5]
let value = _.pullAll(ar, rem)

console.log(value)

let rem = ['b', 'c']
