Is it advisable to learn HTML and JavaScript's at the same time

Answer 1

if you're a beginner i will say take html then css and finally Javascript cause Javascript will frustrate you to the extent that you might wanna quit, but if you know html and css already they will still give you lot of hope not to give up

Answer 2

Well you have already finished the html course here, so it is OK to do JS next or after CSS. It is also OK to go back and revise any tutorial and more importantly practice. Learning never ends.
