For instance, let's have a look at our code. Our starting code will always be referenced by the chapter number and the video number. In this case, 02_02-start. I'll head on over to VS Code where our code is cloned. Now, working in teams where everyone has access to change small things in the code and lack of a unified linter can cause lots of breaking changes. Let's open our sum file and switch from type number to type any in any of the variables passed in our functions. So here, let's say we switch this from number to any, which means it can be anything. And here it can be anything. It might not look like it, but for most code bases, type any can be a pain if you know the exact values to test for.
