Why are runtimes like Deno and languages like TypeScript under the JavaScript category?

Our thinking is that when people think of Deno and TypeScript, they think about them in the context of JavaScript.
​
It's helpful for our authors for us to have "JavaScript ecosystem" categories underneath JavaScript, not just JavaScript frameworks.
​
This way, they also show up in the JavaScript parent category as well (which is helpful), which they would not otherwise unless the author also added the JavaScript category.
​
So, this is why we put certain runtimes and languages under the JavaScript category, and why the Deno category and the TypeScript category are underneath JavaScript...
