You will find out:

- what are objects?

- how to use from objects that are already created?

- how to get any element from the website by ID?

- how to change its value?

- how to create your own objects with methods and properties?

- and many more

• Objects are containers for storing related variables and functions for reuse

• Objects can represent anything that can be seen, like a finger or a building

• Objects are defined by their properties (variables) and actions (functions)

• Built-in objects, like the document object, can be accessed and used in JavaScript

• The document object represents the HTML file and has a method called getElementById which can be used to access elements on the webpage

• Objects can be modified and have their values changed, like updating text on a webpage

• It is possible to create custom objects, like a person object with properties like name and age

• Objects can also have methods, like a greeting method for a person object

• Objects can be created using constructor functions or the class syntax

• Objects can be stored in variables and passed as arguments to functions

• Objects can also be nested inside other objects, like a person object having a job object as a property.

If your script is not working please go ahead and watch section about events, you might need onload event.
