JavaScript. Additional Lessons for Beginners

Why is another book on JavaScript needed? In 2019, the author wrote the book "JavaScript. 20 Lessons for Beginners," which discusses the JavaScript programming language and its use for writing interactive web pages. According to numerous reviews, the book was well received by readers.
Now, two years later, the author is releasing another book on the same topic.
It includes material:
• not included in the previous book due to its limited volume;
• describing innovations in JavaScript that appeared after
the completion of work on the previous book.
It discusses new programming tools that allow:
• endowing pages, websites, and web applications with previously unavailable capabilities (such as recording video, taking photos, chat, or even video telephony);
• significantly simplifying programming and, consequently, increasing programmer productivity.
Like the previous book, it contains:
 

• 20 short, concise, visual lessons, providing essential theoretical knowledge;
• more than 20 practical exercises, performed under the guidance of the author. By completing them, you will reinforce your knowledge and gain programming experience, which your future employer will undoubtedly appreciate;
• 18 exercises designed for self-completion. To handle them, it is enough to carefully study the theoretical material presented in the lessons.
