What exactly does the print function do in apps? Does it do anything important?

Does println or print actually run something in an app?

println or print, only prints to the console. When the user is using an app, they cannot see what is being printed to the console. The only time I use println or print is to see when my code gets executed and to help with debugging.

Hope this helped,
