Challenge Week 4 - Array Manipulation

Case 1 - Using map to Transform and Extract Data

Given an array of objects representing people's information, use the map method to create a new array containing only the names of people.

const people = [
  { id: 1, name: 'Alice', age: 30 },
  { id: 2, name: 'Bob', age: 25 },
  { id: 3, name: 'Charlie', age: 35 },
];

// Expected Output: ['Alice', 'Bob', 'Charlie']

Case 2 - Using filter to Select Specific Data

Given an array of products, use the filter method to create a new array containing only products that are currently in stock.

const products = [
  { id: 1, name: 'Laptop', inStock: true },
  { id: 2, name: 'Phone', inStock: false },
  { id: 3, name: 'Tablet', inStock: true },
  { id: 4, name: 'Headphones', inStock: false },
];

// Expected output: [{ id: 1, name: 'Laptop', inStock: true }, { id: 3, name: 'Tablet', inStock: true }]

Case 3 - Using reduce to Calculate Aggregations

Given an array of numbers, use the reduce method to calculate the total sum of all even numbers in the array.

const numbers = [2, 4, 7, 8, 10, 15];

// Expected Output: 24
