Which framework is used by SoloLearn on its website?

Answer 1

I couldn't find any. As far as I have seen they rely in Facebook and Google APIs, along with their self-made Sololearn API (private uses only)

Answer 2

Probably jQuery, and some other popular frameworks.

Answer 3

Hmm interesting thought. Maybe we can use Inspect Element

Answer 4

The front page of Sololearn has been made with ReactJs.
