Lodash _.unzipWith() Method

Last Updated : 02 Sep, 2024

Lodash_.unzipWith() method accepts iteratee to specify how regrouped values should be combined. The iteratee is invoked with the elements of each group.

Syntax:

_.unzipWith(array, [iteratee = _.identity]);

Parameters:

array: This parameter holds the array of grouped elements to process.
[iteratee = _.identity]: This parameter holds the function to combine regrouped values.

Return Value:

This method returns the new array of regrouped elements.

Example 1: In this example, we are unzipping the given zipped array and using the subtract method for subtracting the values of that array.

JavaScript

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

// Original array
let zipped_arr = _.zip([15, 7], [185, 20], [478, 123]);

// Use of _.unzipWith() method 
let gfg = _.unzipWith(zipped_arr, _.subtract);

// Printing the output  
console.log(gfg);

Output:

[8, 165, 355]

Example 2: In this example, we are unzipping the given zipped array and using the add method for adding the values of that array.

JavaScript

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

// Original array
let zipped_arr = _.zip([4, 9], [185, 20], [478, 123]);

// Use of _.unzipWith() method 
let gfg = _.unzipWith(zipped_arr, _.add);

// Printing the output  
console.log(gfg)

Output:

[13, 205, 601]
