What is the purpose of the map() function in React?
In React, the map()
function is used for transforming arrays of data into arrays of JSX elements, and provides dynamic rendering of lists or collections of items in components. By iterating over each item in an array, map()
allows you to perform operations on data, generate unique keys for efficient list rendering, and construct JSX elements based on data.
