That way every step you take is intentional, leading towards a very clear goal. That's the essence of test-driven development, or TDD. Adopting TDD in Reacts can lead to more predictable, maintainable, and well structured components. Rather than writing code first and testing after, TDD flips the process. So you write a test that defines what your code should do, what should fail, since the functionality doesn't exist yet, write a minimum code needed to make the test pass, refactor for better quality, and repeat the cycle. When you're building React applications, using TDD can be a total game changer. With TDD, you write the test before writing any actual implementation, so you're forced to define exactly what each component should do from the start. This clarity helps you stay focused on building only what is necessary and prevent scope creep. This clarity…
