3. What are the properties and methods in Objects?

A method is a function which is the value of object property and so a task an object can perform. The difference between object properties and methods is to assume the property as a noun and the method as a verb. name, city and profession are all nouns associated with an object, and are properties. code() or talk() are verbs that might be used as a method function definition.

4. Top Difference between “ == “ and “ === “ operators?

== is a comparison operator, The == operator will compare for equality after doing any necessary type conversions.

=== is a strict equality comparison operator, === will not do the conversion, so if two values are not the same type, It will return false.

5. Object.freeze()?

Object.freeze() saves from modification of properties and values of a object and prevents the properties from being added or removed from the object.

// Initialization of an object

const user = {

username: 'Aishu',

password: 'Axios.js'


// Freezing the object

const newUser = Object.freeze(user);

newUser.password = '*'; = true;


Output :

{username: "Aishu", password: "Axios.js"}

Here in this example above, we had tried to override the password Aishu with *, but the password property remained the same and also tried to add a new property, active, but it doesn't add.

Object.isFrozen() is used to determine whether an object has been frozen or not and it returns a Boolean.
