Why is Claude Code, a desktop tool, written in JS? Is the future of all software JS or Typescript?

LLMs are good in JS and Python which means everything from now on will be written in or ported to either of those two languages. So yeah, JS is the future of all software.

This is a common take but language servers bridge the gap well.

Language servers, however, are a pain on Claude code. https://github.com/anthropics/claude-code/issues/15619

It's not a desktop tool, it's a CLI tool.

But a lot of desktop tools are written in JS because it's easy to create multi-platform applications.
