Answer 3

console is very useful tool. This available to browsers. I am not sure for other browsers. But I am sure about Chrome. Because I uses it daily. console is also used to debug your code. Examples if you write a program that calculates two numbers but it is not working. How you will find what is the error in your code? Check out your console by pressing F12 button on your keyboard. You will get an error messages if your javascript code is wrong
