I know that you can print words in the output by function, loops, if statements , ETC. But how can it be useful? For notes? I always thought it was for notes. But I just wanted to fully understand the output.
Oh, thank you very much. I have forgot that it can detect errors. Thank you for reminding me.
The output can be used to print things, yes, however its main purpose is to tell you errors that you have in your code.
The output can be VERY useful. It will help detect errors such as if you're using a color value wrong, or if you have a unknown tag. It can help you fix up even the slightest you mistake, and it could mean a large difference.
VERY USEFUL most of the errors show up on it, so if it wasn't there, you probably would have no idea where to even start fixing your scripts. Even if you don't understand the output, we might, so you can use it for questions too.
