It does have IDE support. VSCode, Visual Studio and WebStorm all support using jsdoc for autocomplete/intellisense.

So, the only thing it doesn't have is compile-time failures and I'm fine with that because I don't really make mistakes that often so I'm not doing a bunch of extra work to identify types for the compiler so it can help me find mistakes.

Famous last words. Everyone makes mistakes. All software has bugs!

But let's grant that you don't for the sake of argument. Is the rest of your team similarly infallible? Even if they are when writing code, will they be able to perfectly parse code they didn't write? What about when you're refactoring and you want to make sure you didn't forget to update any place a function is called? What about when you come back to the code in six months and don't remember what it does? What about when the code changes but you forget to update the JSDoc?

If you're writing something quick and don't have to work with people, sure, I'll buy that types are too much overhead. But when you start doing things at scale, they're a powerful tool for checking and documenting your code.

I’m with you. I actually prefer type systems when the language has them, however I find that languages that transpile to JS come with their own set of problems.

The jsdoc for my code is right next to the code so for all intents and purposes, it is the code. Intellisense for vars is always showing itself, to remind you if the jsdoc type is wrong.

It’s just a trade off, like many things in engineering. Millions of people have been coding in just JavaScript pretty well so far, so I wouldn’t limit the question to just my team.

If you're not making regular mistakes, I suggest you seek more challenging work.

Thank you. I should say that I don’t make that many mistakes when I’m typing in the code.

When I’m designing it, I make plenty of mistakes. When I’m picking out libraries to use, I make plenty of mistakes there too. Most of my mistakes come from architecting things incorrectly like recently, when I chose to make a huge app into an SPA instead of classic web app which would’ve been simpler and would’ve performed just fine.
