Design patterns is not a new concept to computer programmers. Since personal computers became more affordable and popular in the 1980s, the programming profession flourished and a lot of code was written for a variety of applications.
I remember that, when I was 14 years old, learning the GOTO statement for a BASIC program was one of the coolest things. It literally allowed me to take a control flow to a different part of the code at any time. Perhaps not too surprisingly, when I learned about structured programming and the Pascal language in college, I started to realize how GOTO statements produce messy spaghetti code. Using GOTO for branching purposes is a pattern. It's just a bad one because it makes code difficult to understand, follow, and debug. In today's lingua franca, we call them anti-patterns.
