TIL about optional chaining in JS.

I can sleep better tonight.

so

?. <- optional chaining
?? <- nullish coalescing
? <- conditional/ternary operator

dunno why, I can't seem to remember optional chaining off the top of my head.

obj &&
obj.property1 &&
obj.property1.property2 &&
obj.property1.property2.property3

OR

(((obj || {}).property1 || {}).property 2 || {}).property3

It's mostly for projects that don't support Webpack 5 optional chaining (like Vue 2).
I prefer the second one since it's shorter

stateofjs survey reminds me of all that's wrong with JavaScript: too many frameworks each of which has to reinvent the wheel and depend on too many node_modules child dependencies, most don't support TypeScript properly (ever tried to convert a node-express-mongoose tutorial to TS?), there is still no proper type support in JS core language, and browser features get added in form of overly complex APIs instead of handy DOM methods.

Instead the community gets excited about micro-improvements like optional chaining which has been possible in other languages for decades.

At least there is something like TypeScript, but I don't like its syntax either, it's overly verbose and adds too much "Java feeling" to JavaScript in my opinion.

Also there is too much JS in web development, as CSS and HTML seem to have missed adding enough native functionality that works reliable cross browser to build websites in a descriptive way without misunderstanding web dev for application engineering.

After all, I'd rather have frontend PHP than more JavaScript everywhere.

Anyway, at least the survey has the option to choose how satisfied or unsatisfied people are about certain aspects of JS. But I already suspect that most respondents will seem to be very happy and eager to learn the latest hype train frameworks or stick to their beloved React in the future.

How can I test optional chaining in jest?
Should I?
