Challenge: Functional Programming - Use the map Method to Extract Data from an Array
Link to the challenge:
In functional programming, the map() method is used to extract data from an array by creating a new array that contains the same number of elements as the original array, but with each element transformed in some way.
Here’s an example of using the map() method in JavaScript to extract data from an array of objects:
const users = [
{ name: ‘John’, age: 25 },
{ name: ‘Jane’, age: 30 },
{ name: ‘Bob’, age: 20 }
];
const names = users.map(user => user.name);
console.log(names); // Output: [‘John’, ‘Jane’, ‘Bob’]
In this example, the map() method is called on the users array to create a new array called names that contains only the name property of each user object. The user => user.name arrow function is used to specify how each element of the users array should be transformed to create the new names array.
Note that the map() method does not modify the original array, but instead returns a new array. This makes it a pure function, which is a key concept in functional programming.
you can applied it and get desired results i already did it on one of my client site, www dot apkaone dot com
apkaone i tested it on one of the client site.
