0 0 1 minute read

The Lodash _.unset() method is used to remove the property at the path of the object. If the property is removed then it returns True value otherwise, it returns False.

Syntax:

_.unset(object, path)

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

object: This parameter holds the object to modify.
path: This parameter holds the path of the property to unset. It can be an array or string.

Return Value: This method returns true if the property is deleted, else false.

Example 1:

Javascript

// Requiring the lodash library   
const _ = require("lodash");   
  
// The source object  
var obj = { 'cpp': [{ 'java': { 'python': 3 } }] }; 
  
// Use of _.unset() method 
console.log(_.unset(obj, 'cpp[0].java.python')); 
  
// Object is modified 
console.log(obj);

Output:

true
{ cpp: [ { java: {} } ] }

Example 2:

Javascript

// Requiring the lodash library   
const _ = require("lodash");   
  
// The source object  
var obj = { 'cpp': [{ 'java': { 'python': 3 } }] }; 
  
// Use of _.unset() method 
console.log(_.unset(obj, ['html', 'css', 'javascript'])); 
  
// Object 
console.log(obj);

Output:

true
{ cpp: [ { java: [Object] } ] }

Note: This will not work in normal JavaScript because it requires the library lodash to be installed and can be installed using npm install lodash..
