Join Barron Stone for an in-depth discussion in this video Code reuse, part of Programming Foundations: Real-World Examples.
- Eating nothing but omelets would get old real quick.…Variety is the spice of life so I should probably add…another function to my menu of breakfast recipes.…- How about making some pancakes?…- Sounds good to me.…To make a pancake, I start by mixing together…the ingredients in a bowl.…Then I pour that mixture into a frying pan,…I cook the pancake on one side,…flip it, I cook the other side,…and the output of that process,…is a delicious pancake.…Hmm, something seems familiar about this.…Ah, the process for making a pancake has a lot…in common with the process for making an omelet.…
Performing the same steps in multiple places is…the perfect time to consider functionalizing that process.…Back in idle I had the start a 102 breakfast function…scripts open which has a new function for making pancakes.…Inside of the make pancake function,…I perform all of the steps in the pancake making process.…I mix the ingredients, pour the mixture into a frying pan,…cook the first side, flip it, and cook the other side.…At the end, the make pancake function returns a string…
