0 0 1 minute read

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

Syntax:

_.pullAll(array, values)

Parameters: This method accept two parameters as mentioned above and described below:

array: This parameter holds the array that need to be modify.
values: This parameter holds the values in an array that need to be remove from first array.

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

Example 1: This example removing the second array elements from the first array and returns the remaining elements.

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

Here, const _ = require('lodash') is used to import the lodash library into the file.

Output:

[ 2, 4, 5 ]

Example 2: This example removing the second array elements from the first array and returns the remaining elements.

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: This example removing the second array elements from the first array and returns the remaining elements.

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.
