A Trip to Darjeeling with Friends: How JavaScript Helped Us

1. push() - Assembling the Group:

We started with an empty array to keep track of everyone who was going. We used the push() method to add each friend's name to the list.

let darjeelingTrip = [];

darjeelingTrip.push("Koushik");
darjeelingTrip.push("Hitesh");
darjeelingTrip.push("Anirud");
darjeelingTrip.push("Piyush");
darjeelingTrip.push("Akash");
darjeelingTrip.push("Mukul");

console.log(darjeelingTrip); // Output: ["Koushik", "Hitesh", "Anirud", "Piyush", "Akash", "Mukul"]

2. pop() - Dealing with Cancellations:

Unfortunately, some friends had to drop out at the last minute due to personal reasons. We used the pop() method to remove their names from the list.

darjeelingTrip.pop(); // Mukul had to cancel
darjeelingTrip.pop(); // Akash also couldn't make it

console.log(darjeelingTrip); // Output: ["Koushik", "Hitesh", "Anirud", "Piyush"]

3. includes() - Packing Essentials:

Before leaving, we made a list of essential items to pack. We used the includes() method to check if we had everything.

let thingsToPack = ["jacket", "sweater", "camera", "first-aid kit"];

console.log(thingsToPack.includes("jacket")); // Output: true
console.log(thingsToPack.includes("raincoat")); // Output: false

4. find() - Finding a Hotel:

After arriving in Darjeeling, we needed to find a good hotel. We used the find() method to locate a hotel with available rooms.

let hotels = [
  { name: "Hotel Himalaya", available: false },
  { name: "Hotel Red Panda", available: true },
  { name: "Hotel Mount View", available: false },
];

let availableHotel = hotels.find(hotel => hotel.available === true);

console.log(availableHotel); // Output: { name: "Hotel Red Panda", available: true }ode

5. at() - Remembering the Room Number:

After checking in, we got our room number. We used the at() method (or direct indexing) to remember it.

let roomNumbers = ["101", "102", "103", "104"];

let ourRoom = roomNumbers[1]; // Or roomNumbers.at(1);

console.log(ourRoom); // Output: "102"

6. map() - Calculating Sightseeing Costs:

We wanted to visit several places. We used the map() function to calculate the total cost of sightseeing tickets for everyone.

let ticketPrices = [100, 50, 75, 120]; // Prices of different tickets

let totalCost = ticketPrices.map(price => price * darjeelingTrip.length).reduce((sum, price) => sum + price, 0);

console.log(totalCost); // Output: The total cost of tickets

7. concat() - Joining a Trekking Group:

We decided to join a trekking group. We used concat() to combine our group with another group of trekkers.

let ourGroup = ["Koushik", "Hitesh", "Anirud", "Piyush"];
let otherGroup = ["Bulu", "Simran"];

let trekkingGroup = ourGroup.concat(otherGroup);

console.log(trekkingGroup); // Output: ["Koushik", "Hitesh", "Anirud", "Piyush", "Bulu", "Simran"]

8. unshift() - Letting Others Go First:

While waiting in line for the ropeway, we saw some elderly people. We used unshift() to add them to the front of the line.

let ropewayLine = ["Koushik", "Hitesh", "Anirud", "Piyush"];
let elderlyPeople = ["Mr. Das", "Mrs. Roy"];

ropewayLine.unshift(...elderlyPeople);

console.log(ropewayLine); // Output: ["Mr. Das", "Mrs. Roy", "Koushik", "Hitesh", "Anirud", "Piyush"]

9. filter() - Choosing the Best Photos:

After the trip, we had many photos. We used filter() to select the best ones for our album.

let photos = [
  { location: "Tiger Hill", rating: 9 },
  { location: "Batasia Loop", rating: 8 },
  { location: "Peace Pagoda", rating: 7 },
  { location: "Tiger Hill", rating: 10 },
];

let bestPhotos = photos.filter(photo => photo.rating > 8);

console.log(bestPhotos); // Output: The photos with rating above 8

This Darjeeling trip was truly memorable, and JavaScript helped us organize and enjoy it to the fullest. It shows how even simple coding concepts can be useful in everyday situations.
