Practise What You Learn

Hello team, i am new to JS so while following the lessons I tried to practice it on some 3rd party app and wasn’t working … I found the link here that reffers to jsfiddle.net … and I also tried the most easy , drawbox(red) and nothing worked , help please … don’t know if I’m the one doing it wrong .
HELP PLEASE

Hey there,

Functions like drawBox(), pickRandom(), and print() are Grasshopper custom functions that can only be used in the app. You can read more about them in this post.

Hope this helps!
Ben
