Explore Improvements Early

We’ve come a long way with the testing library and have been using TDD the entire time to get us here. Sometimes, it’s important to explore new ideas before a project gets too far. After creating anything, we’ll have insights that we didn’t have at the beginning. And after working with a design for a while, we’ll develop a feel for what we like and what we might want to change.
