As far as I see the finished lessons are ‘greyed out’ and the newly added ones aren’t. You should just pick up those that are added and than back to what you were doing so you’re sure you have picked up the new stuff as well.
If you’re just randomly going through the course it is entirely up to you. Personally I follow the freeCodeCamp lessons order and fill up the gaps if they add new lessons.
As far as I am concerned, there is nothing wrong with learning all the new skills and apply them in your portfolio so you can show off your skills.
I felt that also, zapping though the challenges doesn’t make a dent in memory… but there’s a way.
search tuts for es6 then do
search tuts for regex then do
fcc regular expressions
and so on and so forth.
Thanks for the advice everyone. I did go back and do some of the HTML/CSS tests and it seemed like ‘going backwards’, so moving forward is the way to go
