Road runner Memes

The eternal battle between while-do and do-while loops played out through Road Runner and Wile E. Coyote! On the left, Road Runner safely checks the condition (!edge) before running, saving himself from the cliff. Meanwhile, poor Coyote executes run() first and only checks (!edge) after he's already airborne. And that's why you always validate before executing, folks! The difference between falling and living another day is literally one line of code.

The age-old battle between while loops and do-while loops, perfectly illustrated by Road Runner and Wile E. Coyote! The Road Runner checks conditions before running (while loop), safely avoiding the cliff edge. Meanwhile, poor Coyote executes first and checks conditions later (do-while loop), guaranteeing at least one painful fall into the canyon. This is basically every programmer's first encounter with loop selection coming back to haunt them in production. Some bugs you just can't patch mid-air!
