Answer 1

There are no course what can learn you everything, you need to learn from diferent sources and read documentation.
And most important to practice.

Sololearn can teach you solid level of javascript (enought to build amazing web aplication), but there are always new things added to language, so course cant follow all of this changes.

Answer 2

No, sololearn provides you with the basics – you have to practice yourself.
