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.
