About the Book

Back in 2017 I made a challenge for myself: I wanted to collect 100 things that are useful and I encounter regularly during my work as a Javascript/web developer. To my surprise, I finished in about a week.

Looking at that list I realized that many of them are far from trivial and required in-depth understanding of the technology to solve it. So I wrote short articles about each of them, detailing when that particular problem happens and how to solve it. This was the foundation of a weekly tips newsletter.

Ever since it went online, I've been keeping the content up-to-date, so that when some new version is released or a service goes offline it is reflected in a timely manner. Because of this ongoing maintenance, these tips are as relevant as ever.

This book is the collection of all 100 tips I wrote and polished over the years. It spans a range of topics from elementary Javascript, such as the array destructuring operator and regular expressions, to some more targeted technologies such as RxJS streams and immutable collections. I'm sure you'll find at least some of them that you didn't know about.
