AP CSP: Building the "Busiest Airports" App | Example practice for Unit 6 Lesson 12 or 13

This tutorial walks through building the "Busiest Airports" app in Code.org App Lab (similar to Unit 6, Lesson 12 or 13 transversals make project). We focus on filtering large datasets, using lists (arrays), and implementing conditional logic to display filtered information. https://studio.code.org/projects/appl... 📋 In this tutorial, we cover: Data Import: Bringing the "Busiest Airports" dataset into App Lab. Filtering: Using for loops and if statements to filter data by year (2016) and country. Lists & Arrays: Using appendItem to store filtered data in global lists. Traversal: Building "Next" and "Previous" buttons to navigate through filtered search results. Debugging: Fixing common "undefined" errors and index management. 🚀 Concepts Used: getColumn & Data Import for loops & if logic List Traversal (Index management) Functions & Abstraction (updateScreen, filterData) Local vs. Global Variables ⏱️ Timestamp Guide: 0:00 - Intro: The Busiest Airports Project 2:20 - Importing Data (Data Tables) 5:30 - Creating Global Variables (Lists) 9:40 - Filtering Data: The Two-Part if Statement 16:00 - Writing the onEvent for the Search Button 23:00 - Designing the filterData Function 28:30 - Debugging: Using Watchers to test your code 39:50 - Building updateScreen & Displaying Data 45:30 - Navigation: Coding the "Next" & "Previous" Buttons 51:15 - Fixing "Out of Bounds" Errors with list.length - 1 56:30 - Adding Comments & Final Code Cleanup
