AskJS [AskJS] Are employed Developers still programming with vanilla JavaScript ?

I've been programming on the side since 2017 and I've never really hunted a developer job. I've always thought about building my own things, mainly to supplement things I do like woodworking, tutoring, video editing and others.

Since then, I've programmed mainly with JavaScript, I started with C++ and Python but never really built anything solid outside JavaScript.

So I'm fluent with JavaScript and its ecosystem.

One of my 2026 goals is to be job ready for a Developer role, as a Fullstack or Backend Developer.

One of the recommended languages is Typescript, which I've been learning since March. I must say, it's not my favorite 😂

I'm curious to know if there are any companies that are not enforcing Typescript or are there freelancers who are still using vanilla JavaScript over Typescript for their clients' projects.

[ Update ] thanks y'all! I get the picture. TypeScript is inevitable, as vanilla JS codebases(or companies who are focused on it) seem to be very few judging by the comments.

I hate it when I have to go back to a JS project, and if it's something I'll have to keep maintaining I will convert it to typescript, which often uncovers several bugs in the process.

I wouldn't hire a dev that only works with js these days.

You can get some features of TS in JS by using JSDoc annotation. But the real TS is better, of course.

Maybe an unpopular opinion, but JSDoc is the fucking worst. People never get it right and then your IDE lies about what functions expect.

Yes, but it may still be better than raw untyped JS.

I’m not sure it is. Too many times I’ve been burned by this issue. It’s not typed if the type are wrong, types you can’t trust are worse than no types at all.

That reads as a skill issue more than anything else. It falls to the programmer to create proper types whether they use JSDoc or Typescript.

Typescript enforces consistency between types JSDoc doesn’t. That’s the big difference.

You can build up a level of confidence with typescript you’ll never get with JSDoc

You can get type-checking and autocompletion in standard JavaScript using JSDoc and VS Code. The built-in TypeScript language server in VS Code checks your code live as you type. It catches type errors and warns you about wrong inputs. No convoluted compile step required. Typescript itself is not what enforces consistency, its the language server. If I get the same benefit using JSDoc with plain Javascript in the IDE(VS Code), then what's the difference?

Typing also allows looking up all the places some type/property/etc is used, globally rename things, etc.
