Rubber Duck debugging

“I’ve done everything right, so why doesn’t it work?”

We’ve all been there. You’ve crafted a script or expression that should do exactly what you intended. Except it doesn’t. You stare at the code and scrutinize every expression, but the error still eludes you. In cases like these, Rubber Duck debugging, or Rubberducking, can be a very helpful technique.

What is Rubber Duck debugging?

When you apply Rubber Duck debugging, you explain your code and its expected result step by step in natural language. As the name implies, your counterpart in this exercise is typically a rubber duck. Of course, you can also use other objects, pets, or even non-technical coworkers.

While you explain your code, you’ll (hopefully!) run into a step where the intended action you’re explaining doesn’t match with what’s actually happening. Quack! Eureka! Problem solved.
