Challenge: Implement a Car List Filter with useMemo
Task
Create the CarList component responsible for rendering a list of cars and providing a search functionality to filter them based on their names. It allows users to enter a search term and dynamically filters the list of cars based on that input.
Instructions
- Import the necessary hooks from the React library.
- Inside the
CarListcomponent, declare a state variablesearchInputand a state updater functionsetSearchInputusing theuseStatehook. InitializesearchInputwith an empty string. - Use the
useMemohook to memoize thefilteredCarsarray. The memoization logic should filter the cars based on thesearchInput. IfsearchInputis empty, return all cars; otherwise, filter the cars based on the search input. - In the
useMemodependency array, specify the correct variables the memoized function depends on.
- Include an
importstatement to import the necessary hook from the React library. - Use theΒ
useStateΒ hook to declare a state variable and its updater function. - TheΒ
useMemoΒ hook memoizes the filtered cars array, preventing unnecessary recalculations. - In the dependency array ofΒ
useMemo, include the variables that the memoized function depends on (carsΒ andΒsearchInput).
