What a Tool!

Issue #326  (JS Infinity, React Tools, Text Editors, Uncats)

Last month I started to write a quick tip on the Infinity value in JavaScript. As I looked up the topic in various references and books, I realized there are quite a few little quirks and interesting facts surrounding Infinity and how it's used as a numeric value.

So I wrote a full blog post on the subject:

The article includes 8 different CodePen demos and covers when Infinity is returned, what the threshold for Infinity is, negative Infinity, and lots more. And if you want more JavaScript quick tips, you'll enjoy my e-books bundle available via Leanpub (you can also buy the books individually if you don't want to buy all three).
 

Now on to this week's tools!
