What is a document here? and how a document and browser console becomes an object?

Hello, As mentioned in the video. A string, Document & Browser Console are objects. A document i guess the app.js is a document and console is where we see what JS is writing to the console for messages or errors. How come a document and Browser console becomes an object. Can anyone explain please.

Also what other objects exist in the JS?

Thanks in advance

Right. Here goes.

When you are calling document.write(), you are modifying the HTML document that is calling your javascript. It will modify the document at the spot where the javascript was called.

So if you were to make a heading tag and then insert some javascript code there, either as raw script or as a link to the code, and that code went and executed a document.write('hello') then what would happen is the text hello would be inserted in between those <h1></h1> tags where you called the script.

The console method is just writing something out to your javascript console. Helps to debug your code. Regular web users would not see that because they don't normally display that console in their browser. Besides you should have that removed before you push your page out to the public. ;)

Finally, LOTS AND LOTS of object types are built in. And the crazy part, with object oriented javascript (you will learn later) you can make your OWN object types!!! :D

It is going to be a blast! Keep up the great work! :)
