Awesome books: plain JavaScript with objects

[oliverSCZ]

I did the following:

• Created a GitHub repo entitled, 'awesome-books'.
• Created a new branch, 'add-javascript' from main in accordance with GitHub flow rules.
• Added all files required and followed the necessary instructions (.gitignore, .html, .css, test.md, README.md).
• Committed files (as required).
• Effectively set up a HTML & CSS & JS linter.
• Ensured that irrelevant files were ignored by Git.
• Documented my work professionally and added a descriptive README.md file to the project's repository using the template provided.
• I did that by using JavaScript objects and arrays. And also I did dynamically modifying the DOM and adding basic events.
• Opened this pull request as instructed.
