Hi Vehbi,

IDEs and most Text Editors will highlight most spelling errors and syntax errors, but none can nor will (for the most part) show you logic errors, misused variables, variables out-of-scope, mislabeled variables, functional errors, programmatic errors, or any other errors that are directly related to the function, scope and use of the app.

From where you are linking this post from, Error Handling is essential especially when taking in user input. You don't receive this input until your app is live, so how could your Text Editor highlight an error for you if it has no idea of the data being used?

A complete explanation does go a bit beyond the scope of the Community, but it should become more clear and evident as you progress through the course.

Hope that helps a bit! :) :dizzy:
