I tried out the following console methods

1. console.log('This is a log');

2. console.warn('This is a warning');

3. console.error('This is an error');

4. console.info('This is an information');

5. console.debug('This is a debug');

6. let books = [

                { bookname: 'Recursion Sutras', subject: "Recursion" },

                { bookname: 'How to do Object Oriented Programming', subject: "OOPS" },

];

            console.table(books);

7. let books = [

                { bookname: 'Recursion Sutras', subject: "Recursion" },

                { bookname: 'How to do Object Oriented Programming', subject: "OOPS" },

];

            console.dir(books);

8. console.log('%c This is a great book, %c This is a greater book', 'font-size:40px;color:brown;background-color:green;', 'font-size:48px;color:green;background-color:brown;');
