    Instructor: 0:00 Hi, there. This is our "Fundamentals of Testing in JavaScript" module. I'm super excited for you to go through this because we're going to build our own little miniature version of Jest, so you get an understanding of what that tool does and how it works from a fundamental level.

    0:15 The way that this project is structured is, we have this lessons directory that has a file for each one of the lessons, and then a math module that we'll be testing through the course of this module. I think it's really important for people to understand how their abstractions work, so they can use them effectively. I know you're going to really love this one.
