How are Objects Stored

Lecture 149:- How are Objects Stored

In JavaScript, objects are stored as reference types. When an object is created, a reference to that object is created and stored in memory. The reference itself is a variable that holds a unique identifier to the memory location of the object.

When you create an object in JavaScript, the actual object is created in memory, and the reference to that object is returned. When you assign an object to a variable or pass it as an argument to a function, you're actually passing a reference to the object in memory.

For example, consider the following code:

bashCopy code

let person = {  name: "John",  age: 30, }; let anotherPerson = person;

In this code, we create an object called person with two properties: name and age. We then create another variable called anotherPerson and assign it the value of person. What's important to understand here is that anotherPerson does not create a new object. Instead, it creates a reference to the same object that person is referencing.

So, any changes made to the person object will also be reflected in the anotherPerson object because they are both referencing the same object in memory.
