Slide 1 ----------- Part 1: Let's practice pure components! Slide 2 ----------- Part 1: Your task is to implement a React app with the following requirements. Part 2: A "CounterDisplay" component displays the counter value and updates only when the counter changes. Part 3: A "StaticMessage" component displays a static message and should not re-render unless its props explicitly change. Part 4: Use React.memo to optimise the child components. Slide 3 ----------- Part 1: Again, you can depend on your tests to check if your solution is correct! Part 2: This time, pay close attention to the console and the messages within Part 3: The messages produced by your tests will follow the suite name ... Part 4: ... finished by the test name and result. Good luck!
