Frontend

Lots of new faces here – welcome, fellow HTML renderers! ✨

Let's do some introductions:

1. What's your favorite HTML/CSS/JavaScript feature?
2. What are you currently using /frontend technology to build?
3. What framework, library or stack are you hoping to learn, or think more people should know about?

Extra bonus if you include links to developer.mozilla.org and GitHub!

1. I love optional chaining - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining 🫶
2. Currently building a renting platform for otherside assets at Zharta - https://www.zharta.io/otherside-renting 🚀
3. Excited to dive into Three.js, wrapping up Bruno Simon’s course🔮

The `?.` operator is awesome! Makes dealing with `null` and `undefined` incredibly easy.

Pairs well with `| undefined` in TypeScript too!

Yeah! `??=` is super handy for assigning default fallback values imperatively.

I remember my rails arc when some methods were called with ! for side effects and ? for booleanish methods.

We have other cool operators on ts

let foo
foo ?= “set if missing”

Or

Const val = variable ?? “Set only if nullish value on variable”

Maybe, though in my experience allowing something to be undefined then using `?.` / `??` is the quickest way to write branching/fallback logic.

Better than what we had before which was to write the property access expression twice with an `||`.
