Is SoloLearn's JavaScript tutorial enough for solving challenges?

Question

Hi, I feel like JS tutorial on SoloLearn is lacking some info to successfully solve all the JS challenges.
Am I right or wrong?

Answer 1

Nope they are perfectly in the course.
Else it would end up in the reviewers' bin

Answer 2

No you'll need more and advanced courses

Answer 3

You must to practice day by day and auto challenge with diary problems. If you want to coding something you will do step by step ;-)

Answer 4

That's rubbish. Course should allow us to do majority of challenges...
I've started using SL because it was convenient but it turns out to be insufficient at all levels.
