"Fake it till you make it" is a concept that programmers use everyday. We simply don't want to wait until we are completely done writing a program to see it run, so we 'fake' out some part.
For example:
Let's say we had a program which drew a flower, and we wanted the color of that flower to match with the weather outside. Now, it's a bit of programming to find out the weather and match it with a color. I'd like to see if the flower looked good first, so I'd create a subroutine that just assumes it is sunny
Sub GetColorToMatchCurrentWeather
GraphicsWindow.penColor = "yellow"
EndSub
Now, that I've
faked that part of the code, I don't have to deal with it until i'm ready.
