Yes, you need to write code in pure Angular in the Stackblitz website, but it's inconvenient for me personally, so I used the AngularJS library in Sololearn, since it is very similar and can be used in any html document.

By the way, in Sololearn, you can also scatter everything into separate files: html, CSS, JavaScript.
