WalkthroughThe pull request updates the project’s README by changing the project name from “[Project Name]” to “DestINo” and introduces an AI Travel Itinerary Planner feature. The new functionality includes an HTML interface (index.html) with a travel inputs form, a JavaScript file (script.js) that defines destination data and implements functions to generate itineraries and export them as PDF files using the jsPDF library, and a CSS file (styles.css) to style the interface elements. The changes focus on integrating itinerary planning logic and a structured, styled user interface while preserving existing content. Changes

Add missing destination data to match UI options.
The destinationData object is missing data for London, Rome, Sydney, and Dubai, which are available as options in the UI. This mismatch will result in "Sorry, we don't have data for this destination" errors when users select these destinations.
Consider internationalizing costs.
The costs are hardcoded without currency specification. Consider:
- Adding currency information to support international destinations
- Implementing currency conversion based on user preferences

🛠️ Refactor suggestion
Improve PDF export functionality.
The current implementation has several limitations:
- No error handling if itinerary is not generated
- Basic PDF formatting with all text at position (10,10)
- No handling of content overflow or page breaks
Here's a suggested improvement:
function exportItinerary() {
+ const itineraryElement = document.getElementById('itinerary-summary');
+ if (!itineraryElement || !itineraryElement.innerText.trim()) {
+ alert("Please generate an itinerary first.");
+ return;
+ }
+
const { jsPDF } = window.jspdf;
const doc = new jsPDF();
- const itineraryContent = document.getElementById('itinerary-summary').innerText;
- doc.text(itineraryContent, 10, 10);
+ // Set font size and line height
+ doc.setFontSize(12);
+ const lineHeight = 8;
+
+ // Split text into lines that fit the page width
+ const lines = doc.splitTextToSize(itineraryElement.innerText, 190);
+
+ // Add lines to PDF with proper spacing
+ let y = 20;
+ lines.forEach(line => {
+ if (y > 280) { // Check if we need a new page
+ doc.addPage();
+ y = 20;
+ }
+ doc.text(line, 10, y);
+ y += lineHeight;
+ });
+
doc.save('itinerary.pdf');

Several improvements needed for the itinerary generation logic.
- Trip dates from the UI are not used in the itinerary generation
- The 3-night stay assumption for accommodation budget is hardcoded
- Missing error handling for cases where no activities/accommodations fit within budget
- HTML content is not sanitized against XSS attacks
- No consideration for seasonal availability or operating hours of activities
Here's a suggested improvement:
function generateItinerary() {
const destination = document.getElementById('destination').value;
const budget = parseFloat(document.getElementById('budget').value);
+ const startDate = new Date(document.getElementById('start-date').value);
+ const endDate = new Date(document.getElementById('end-date').value);
+
+ // Validate dates
+ if (isNaN(startDate.getTime()) || isNaN(endDate.getTime()) || startDate >= endDate) {
+ alert("Please enter valid trip dates.");
+ return;
+ }
+
+ // Calculate number of nights
+ const nights = Math.ceil((endDate - startDate) / (1000 * 60 * 60 * 24));
if (!destination || isNaN(budget) || budget <= 0) {
alert("Please enter a valid destination and budget.");
return;
}
// Check if the destination is in the predefined data
const data = destinationData[destination];
if (!data) {
alert("Sorry, we don't have data for this destination.");
return;
}
// Suggest activities based on the budget
let activities = data.activities.filter(activity => activity.cost <= budget);
- let accommodations = data.accommodations.filter(acc => acc.costPerNight <= budget / 3); // Assume a 3-night stay
+ let accommodations = data.accommodations.filter(acc => acc.costPerNight <= budget / nights);
+
+ // Check if we found any suitable options
+ if (activities.length === 0 || accommodations.length === 0) {
+ alert("Sorry, we couldn't find any suitable activities or accommodations within your budget.");
+ return;
+ }
// Generate itinerary summary
let itinerarySummary = `
<h3>Destination: ${destination}</h3>
+ <h4>Trip Duration: ${nights} nights (${startDate.toLocaleDateString()} - ${endDate.toLocaleDateString()})</h4>
<h4>Activities (within your budget):</h4>
<ul>
- ${activities.map(activity => `<li>${activity.name} - $${activity.cost}</li>`).join('')}
