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'); Â Â let ar = [1, 2, 3, 4, 5] Â Â let rem = [1, 3] Â Â let value = _.pullAll(ar, rem) Â Â 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'); Â Â let ar = [1, 2, 3, 1, 3, 4, 1, 5] Â Â let rem = [1, 4, 5] Â Â let value = _.pullAll(ar, rem) Â Â 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'); Â Â let ar = ['a', 'b', 'c', 'd'] Â Â let rem = ['b', 'c'] Â Â let value = _.pullAll(ar, rem) Â Â console.log(value) |
Output:
[ 'a', 'd' ]
Note: This will not work in normal JavaScript because it requires the library lodash to be installed.
