List Rendering in React with map()
In React, we can dynamically render lists using JavaScript's map() function. This method allows you to iterate over arrays and generate elements for each item in the array.
Synopsis
Using map() is an efficient way to render lists of elements in React. It can be used to iterate over an array of data and return a component or JSX for each element.
- map(): The JavaScript function used to iterate over an array and return a new array with modified or transformed elements.
Purpose
List rendering is one of the most common tasks when working with dynamic data in React. By using map(), you can efficiently create components without having to write a lot of repetitive code.
- Create dynamic lists based on array data.
- Use key to optimize list rendering.
