Do you have an alternative suggestion? Because the ability to type "." and see what comes next, go-to-definition, find all references, rename symbol, etc. are all enormous time savers.
Just as yanis_t said, they're easily worth it even if you ignore the significant bug reduction (approximately 15%).
I don't know of any other way to get that kind of productivity boost. What would you suggest instead?
VSCode and other IDEs can do . completion, go to def, rename, etc on plain JavaScript. That's not a unique feature of typed languages.
But find all references doesn't actually work without typescript if your data is passed around enough, and that's an important one for refactoring.
No they don't. They can make a decent guess occasionally but it's not remotely the same as in typed languages where it's accurate and works all the time.
It is absolutely a unique feature of typed languages.
In far fewer cases.
