How do I handle lists in React?
In React, you can handle lists using the map()
function to render each item. Do you have a specific example in mind?
Yes, I want to display a list of tasks.
You can create an array of tasks and use map()
to iterate over it. Here's a simple example:
const tasks = ['Task 1', 'Task 2', 'Task 3'];
function TaskList() {
return (
<ul>
{tasks.map((task, index) => (
<li key={index}>{task}</li>
))}
</ul>
);
}
This will render each task in an unordered list.
What about adding a unique key for each item?
Great question! It's important to use a unique key for each item to help React identify which items have changed. If your tasks have unique IDs, use those as keys instead of the index.
