Code coverage is an important part of building applications because it checks how much source code is executed when tests and other files run. A development dependency for nyc was added to package.json, which efficiently checks code coverage depending on parameters. A command for code coverage was also added to "tests" in package.json, where the --all flag was set so that not only can you check test files but others as well. Additionally, a command for checking nyc reports was added.
