Map, Set, and macOS Catalina

JavaScript data structures and setting up a new MacBook

Happy Tuesday! It’s Tania. I have one new article for you today, and one revised article.

Understanding Map and Set in JavaScript

If you’re familiar with Objects and Arrays but haven’t gotten around to using Map and Set yet, take a look at this article. Set in particular is extremely useful for working with unique values, and Map adds a lot of functionality to key/value pair storage.

macOS Catalina 10.15: Setting up a Brand New Mac for Development

I originally wrote this article in 2015/2016 and I’ve revised it here and there, but it needed a total overhaul as my career has evolved. I’ve had to set up a few Macs recently, and I like having one place to look to do all my initial setup. It’s an opinionated guide, but it might help you out if you’re a web/JS developer setting up a Mac.

That’s all for today, have a nice week!
