✅Unit tests help identify and fix bugs early in the development process, leading to higher quality code.
📝Unit tests serve as documentation for how our functions should behave, making it easier for others to understand and maintain the project.
🔄Unit tests enable confident refactoring of code, allowing for changes in structure without breaking functionality.
⏱️Unit tests can be written efficiently and run in seconds using test runners, saving time and resources.
