If you care more about development experience than users, that's fine, but in the case of SPA, JS frameworks will be faster and lighter.

For me the problem with TypeScript is not the language, JS/TS are fine for me, the problem is the entire toolchain - NodeJS, all the node_modules, configuration files, the need to compile.

Maybe Svelte, where they got rid of TypeScript and the types are now in JSDoc, could be a compromise.
