It is quite common to start a script with a few basic lines of code to get the initial part of a script functioning. Once you have your first basic version running, you will go through many iterations to tweak and enhance it so that it behaves just the way you want it to.

The auto-reload feature will become your best friend during these intensive coding sessions as it will let you get results much faster and in an intuitive way.
