As someone who works with typescript daily, you’re not wrong. It’s an extremely overcomplicated glorified linter that tries and mostly succeeds in catching basic type errors. But it also provides false confidence when you concoct something that shows no errors but doesn’t behave how you expect.
Good riddance, I say. Web dev is infested with layers upon layers of tools that attempt to abstract what is already fairly simple and straightforward to work with. We’re beyond the days of needing to build buttons out of small image fragments, and JS is (slowly) becoming more livable in its raw form. I welcome anything that keeps the toolchain as simple as possible.
