Lodash _.zipObject() Method

0 0 1 minute read

The _.zipObject() method is used to combine two arrays into an object one array as keys and the other as values.

Syntax:

_.zipObject([props=[]], [values=[]])

Parameters: This method accepts two parameters as mentioned above and described below:

[props=[]](array): This parameter holds the property identifiers.
[values=[]](array): This parameter holds the property values.

Return Value: This method returns an object containing key values corresponding to the given array.

Example 1:

Javascript

const _ = require('lodash'); 
  
let x = ['a', 'b', 'c']; 
  
let y = [1, 2, 3] 
  
let obj = _.zipObject(x, y) 
  
console.log(obj);

Here, const _ = require(‘lodash’) is used to import the lodash library into the file.
Output:

{ a: 1, b: 2, c: 3 }

Example 2:

Javascript

const _ = require('lodash'); 
  
let x = ['name', ';language', 'used']; 
  
let y = ['lodash', 'JavaScript', 'nodejs'] 
  
let obj = _.zipObject(x, y) 
  
console.log(obj);

Output:

{ name: 'lodash', ';language': 'JavaScript', used: 'nodejs' }

Example 3: If you pass an extra key and no values for it, it will put undefined value associated with that key.

Javascript

const _ = require('lodash'); 
  
let x = ['a', 'b', 'c', 'd']; 
  
let y = [1, 2, 3] 
  
let obj = _.zipObject(x, y) 
  
console.log(obj);

Output:

{ a: 1, b: 2, c: 3, d: undefined }

Example 4: If you pass an extra value and no key for it, it will ignore that value.

Javascript

const _ = require('lodash'); 
  
let x = ['a', 'b', 'c']; 
  
let y = [1, 2, 3, 4] 
  
let obj = _.zipObject(x, y) 
  
console.log(obj);

Output:

{ a: 1, b: 2, c: 3 }

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