 I have been mulling in my head for a while now about how I wanted to talk about this very common design pattern at work. [Designing by contract](https://en.wikipedia.org/wiki/Design_by_contract) is a very old idea in software and I have found myself having to explain it and teach it other developers at work. So hopefully in this post, I can elaborate on why using a contract is beneficial in the design and development of large applications.
