Lodash _.pullAllWith() Method
Lodash_.pullAllWith() method is similar to the _.pullAll() method that returns the first array containing the values that are in the first array not in the second array but in _.pullAllWith() all the elements of the first array are compared with the second array by applying comparison provided in third. It may be a little complex to understand by reading this but it will become simple when you see the example.
Syntax:
_.pullAllWith(array, values, [comparator]);
Parameters:
- array: This parameter holds the array that needs to be modified.
- values: This parameter holds the value that needs to be removed.
- comparator: This parameter holds the comparison invoked per element.
Return Value:
This method returns an array.
Example 1: In this example, we are removing the giving array from another array that has the same value as it and printing the result in the console.
Javascript
// Requiring the lodash library const _ = require( "lodash" ); // Original array let x = [1, 2, 3] // Value array to be subtracted let y = [2, 4, 5] // Printing the original array console.log( "Before : " , x); // Array after _.pullAllWith() // method where _.isEqual is the // comparator _.pullAllWith(x, y, _.isEqual); // Printing the output console.log( "After : " , x); |
Output:
Example 2: In this example, we are removing the giving array from another array that has the same value as it and printing the result in the console.
Javascript
// Requiring the lodash library const _ = require( "lodash" ); // Original array let x = [{ a: 1 }, { b: 2 }, 6] // Value array to be subtracted let y = [{ a: 1 }, 7, 6] // Printing the original array console.log( "Before : " , x); // Array after _.pullAllWith() // method where _.isEqual is the // comparator _.pullAllWith(x, y, _.isEqual); // Printing the output console.log( "After : " , x); |
Output:
