fill not defined in JavaScript?

Question

So I am making a number analyzer code in JavaScript and previously i was using https://www.khanacademy.org to write the code and run it in their live editor but that doesn't allow me to run window.prompt so i shifted to some other editors but all of them are giving me an error when I try to fill something with color like this:

fill (255, 0, 0);

error: JavaScript error: Uncaught ReferenceError: fill is not defined on line 3 why is this happening and how can i fix it?

Answer 1

fill is an helper function that is only available in your course environment. window.prompt is probably disabled to avoid pranks that show thousand of dialogs lol
