What does the numbers in the curly brackets after the code type mean in (github) markdown? Couldn't find any docs about it

    ```js{6, 15}
    export default {
      setup() {
        const input = ref(null)
        // ...
        return {
          input
        }
      }
    }
    ```

Found it in multiple docs across frontend frameworks

This doesn't seem to be for Markdown processed by GitHub, but VitePress. Specifically, this syntax is for line highlighting: js{6, 15} highlights lines 6 and 15 in the code block.
