It started as a challenge

I was curious whether I could collect 100 useful things related to web development. It turned out it's not a hard challenge.

Alternatively, you can get all 100 in a book, in one convenient place.

How to shuffle an Array, how to generate proper random numbers, how to secure 3rd-party dependencies

A lot of topics are covered in these articles. I was constantly surprised how deep each topic was and how complicated things were once I started looking. I never imagined undefined could have so many edge cases, for example.

At one point I needed to shuffle an Array. Searching for a solution online, it's easy to find a short one-liner that is wrong. The proper solution is a bit more involved.

Later I needed to upload a zip file to a webapp and I did not want to lose the contents on page refresh. It turned out that storing binary data in localStorage is possible, though it's not simple.

This book is full of problems like these: little things that you might not give a second thought, but scratching the surface reveals a surprising depth. And by learning about these, you'll understand web development on a whole new level.
