It’s native typescript.
A lot of fortune 500 companies with some developers who missed the trendy stuff still do it that way. I made a medium size website (30 pages) in React with pure javascript and dependencies being script tags in index.html to vendored files.
So not even JSX. I did it that way because it was the easiest way to develop and deploy in that environment
<script type="module">
``` #!/use/bin/env node
console.log("hello cli") ```
While it does depend on node, and there are arguably better crossplatform languages for this purpose, it is a zero-tool chain use case that is very convenient for us.
And the group mentioned is (I deduce) not generally individual devs, enterprise devs building some internal thing, and so on but teams in companies doing public-facing SaaS, teams in startups, companies like Amazon/Google/Facebook/Apple all the way to AirBnB etc, and so on.
So, you don't really need stats for that.
