So there's a plugin for this, which can be used as follows in Markdown:

<CodeSwitcher :languages="{py:'Python', r:'R', js:'JavaScript'}">
<template v-slot:py>

```python
# Bye world in Python 3
print("Bye World")
```

</template>
<template v-slot:r>

```r
# Bye World in R
cat("Bye world\n")
```

</template>
<template v-slot:js>

```js
// Bye world in JavaScript
console.log("Bye World");
```

**Note:** JS is crazy!

</template>
</CodeSwitcher>

The newlines after <template> and before </template> are required for correct rendering of Markdown.

I've asked the developer whether it's possible to avoid the repetitive :languages="{py:'Python', r:'R', js:'JavaScript'}", see padarom/vuepress-plugin-code-switcher#5 - so maybe it gets a bit simpler soon. For now, just copy & paste it and we can remove it later again, if they choose to implement it.

Closing here, as there's no ToDo anymore for me. Mentioned in #16 instead so that there's a reference to the related PR.
