What will I learn?
This short, practical Jest Course teaches you how to set up a testing environment, write clear unit tests, and design testable JavaScript modules with immutable APIs. You will practice testing task management logic, date utilities, and time-dependent behavior using mocks, spies, and timers, then improve test quality with solid structure, coverage, and CI integration for reliable, maintainable code.
