Lodash _.unzip() Method

Lodash _.unzip method is similar to _.zip (i.e.; it creates an array of grouped elements) except that it accepts an array of grouped elements and also creates an array regrouping the elements to their pre-zip configuration.

Syntax:

_.unzip(array);

Parameters:

• array (Array): This parameter holds the array of grouped elements to process.

Return Value:

This method is used to return the new array of regrouped elements.

Example 1: In this example, we are grouping the given array by the use of the lodash _.unzip() method.

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

// Original array 
let zipped = _.zip(['a', 'b'], [1, 2], [true,
    false]);

// Use of _.zip() 
// method
let gfg = _.zip(zipped);

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

Output:

[ [['a', 1, true], ['b', 2, false]] ]

Example 2: In this example, we are grouping the given array by the use of the lodash _.unzip() method.

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

// Original array 
let zipped = (['x', 'y'], [5, 6], [true, false]);

// Use of _.zip() 
// method
let gfg = _.zip(zipped);

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

Output:

[ [true, false] ]

Note: This code will not work in normal JavaScript because it requires the library lodash to be installed.
