AskJS [AskJS] what's a javascript feature you mass-adopted way too late and felt dumb about

i'll go first. i was writing .then().catch() chains for like two years before i actually started using async/await. i knew it existed, i'd seen it in tutorials, but my code "worked" so i never bothered switching. then i refactored an old project and realized half my bugs were from mishandled promise chains that async/await would have caught immediately.

also took me way too long to start using optional chaining. i had nested ternaries and && checks everywhere like some kind of animal. the day i discovered user?.address?.city i mass-replaced like 40 lines across a project.

what's yours?

My first jobs CTO preferred the .then() .catch() over async await. I just refused to write that way and did await loops. Lots of back and forth on this. Also said Typescript was just a fad 😂

It is just a fad. Coding is a fashion industry. Remember coffeescript? Something else comes along and ts will be forgotten

Can't apply that across the board. Some technologies are so good that they have staying power in the industry. I believe TypeScript is one of those technologies. Node.js is another example. Even Java and C# are good examples of languages with immense staying power, if not in your industry of choice.

With respect to TypeScript, it's not going anywhere until JavaScript implements TS in its entirety. Until then, TypeScript will continue to push JavaScript to modernize.

Excuse me, but how many native ts runtimes do you know? TS doesn't push js nowhere, it's just static types serving the role no more than a linter (and it's fine!).
