Lodash _.difference() Function

Lodash _.difference() function is used to remove a single element or the array of elements from the original array. This function works pretty much the same as the core function of JavaScript i.e. filter.

Syntax:

_.difference(array, [values]);

Parameters:

• array: It is the array from which different elements are to be removed.
• values: It is the array of values that are to be removed from the original array.

Note: We can use a single value or an array of values. But if only a single Integer is given then it will not affect the original array.

Return Value:

This method returns a new array.

Example 1: In this example, we are using the _.difference() method to find the difference of the array. 

Javascript

// Requiring the lodash library
let _ = require("lodash");

// Original array
let array = ["a", 2, 3];

// Values to be removed from
// the original array
let values = [2, 3]
let newArray = _.difference(array, values);
console.log("Before: ", array);

// Printing array
console.log("After: ", newArray);

Output:

Example 2: In this example, we are using the _.difference() method to find the difference of the array. When an empty array is given, there will be no change in the original array.

Javascript

// Requiring the lodash library
let _ = require("lodash");

// Original array
let array = ["a", 2, 3];

// Values to be removed from
// the original array
let values = []
let newArray = _.difference(array, values);
console.log("Before: ", array);

// Printing array
console.log("After: ", newArray);

Output:

Note: This function returns the original array if the value array is single value, empty array or object of arrays.
