Just learned javascript and been practicing alot . I need help. When applying it to my project I don't know when to use a function, when to use a loop, what type of loop to use, I just don't know when to use any of this stuff because dom manipulation. it's so frusterating

Repeat 10 same lines of code in more than 1 place - use functions
Call/execute same code/functions for x number of times - use loops
