Notes

// Define an array of objects (people)
const people = [
{ name: 'Alice', age: 25 },
{ name: 'Bob', age: 30 },
{ name: 'Charlie', age: 35 },
{ name: 'Diana', age: 40 }
];

// // 1. Use forEach to iterate over the array and log details
// console.log('Using forEach to log details:');

// people.forEach(p => { console.log(`Name: ${p.name}, Age: ${p.age}`)})

// // 2. Define a callback function that processes and logs the person's details
// function logPersonDetails(person) {
// console.log(`Callback - Name: ${person.name}, Age: ${person.age}`);
// }

// // Use the callback function with forEach
// console.log('Using callback with forEach:');
// people.forEach(logPersonDetails);

// 3. Use an arrow function to filter out people older than 30
// const olderThan30 = people.filter(person => person.age >= 30 && person.age <= 35);
// console.log('People older than 30:', olderThan30);

// filfun = (per) =>{if(per.age >= 30 && per.age <= 35) return per ;}
// const olderThan30n = people.filter(filfun);
// console.log(olderThan30n)


// 4. Use a promise to simulate asynchronous processing
const processPeopleAsync = () => {
return new Promise((resolve, reject) => {
setTimeout(() => {
console.log('Promise is Resolved ')
resolve(people);

// reject('Failed to process data'); // Uncomment to simulate an error
}, 9000); // Simulate a delay of 2 seconds
});
};

// 5. Use async/await to handle the promise
const getProcessedPeople = async () => {
try {
console.log('Processing data...');
const processedPeople = await processPeopleAsync();
console.log('Processed People:', processedPeople);
} catch (error) {
console.error('Error:', error);
}
};

// // Fetch and process the people data
getProcessedPeople();
