Course details

Most software engineers would agree that clean code is easier to maintain than messy code, but what exactly does that look like, and how do go about cleaning up messy code? In this course, Jon Peck shows how to measure quality, implement testing, and measure code coverage in your Node.js apps, using a complete but buggy restaurant booking application to illustrate the concepts. Jon first reviews JavaScript fundamentals and testing and code quality concepts. He then explains how to use linters to find suspicious code; explores different testing frameworks and their components; and shows how to isolate your code for testing using test doubles, then verify with spies and mocks. Jon wraps up the course by showing how to generate reports on code health across your entire codebase. Along the way, he provides challenge and solution videos so you can test your knowledge of each section before moving on.

    Very helpful to me to understand the topic, thank you! Unfortunately, I was derailed a few times because the software shown has changed quite dramatically in some cases. I'll have to leave the course now understanding Linting and the high levels of the other testing and will return to the testing topics when I have more experience under my belt.

    The main concepts discussed in the course was eye opening. I would recommend it overall. However, it would be nice if the author could update the material with more recent versions of the tools (for example ESLint is now using a new flat config format instead of eslintrc). Also adding more recent standards could be nice to see, like import statements instead of require, and TypeScript support.
