Many of the most pleasant codebases I have worked with were built before TypeScript existed. Building a good codebase takes a lot of care and thought and can't come just from using TypeScript, in fact the worst cases I can remember happen to be TypeScript. By no means am I saying TypeScript is the reason these codebases were poor, however it also didn't seem to help them all that much.
