I am confused to learn what, on my campus I learn C ++ for semester 1, and Java for semester 2 but I want to also learn javascri

well, only learn js once youve learnes html and css

The problem is the syntax. While all these languages are different, their syntax is very similar and it will be easy to get confused at a critical moment, like an exam.

i was learned HTML and Css @Joshua

okay, then switch java with js

you got sololearn Learn langages here,

In my opinion,you'd better keep learning one language until u do really professional enough.For example, In C you can pass by value or pass by reference,but in java,you could only pass by value and there is no pointer in java. you may in a mess.
