TypeScript arrays and objects for QA automation — typed arrays, tuples, interfaces, and the array methods (map, forEach, filter) that power every real-world test framework. In this video, we extend your TypeScript toolbox from individual primitives into structured collections. We type our arrays so the wrong data can't sneak in, lock down credential pairs with tuples, transform data with map/forEach/filter, and model real API payloads with objects and interfaces. ⏱ Timestamps: 0:00 — Organizing your toolbox 0:58 — Typed Arrays 2:30 — Tuples 3:40 — Array Methods: map, forEach, filter 7:08 — Objects & Interfaces 10:23 — Summary 🎯 Homework: Find a test in your project that uses multiple related variables. Refactor it to use a single object with an interface. You'll immediately see how much cleaner your code becomes. 📚 Resources mentioned: - Episode 2 source code (episode_02.ts) in the series folder 📝 Related blog post: https://idavidov.eu/how-to-use-arrays-and-objects-in-typescript-for-powerful-qa-automation-scripts 🚀 Level up your Playwright: - 33 Playwright Tips & Tricks (FREE PDF): https://buymeacoffee.com/idavidov/e/501071 - AI-Native Playwright Scaffold — 16 skills, zero config: https://buymeacoffee.com/idavidov/e/513835 - 1:1 Playwright Architecture & Troubleshooting Session: https://buymeacoffee.com/idavidov/e/504261 - Browse all my products: https://buymeacoffee.com/idavidov/extras Subscribe for @ArchQA 🔗 Connect with me: - Blog: https://idavidov.eu - LinkedIn: https://www.linkedin.com/in/ivdavidov/ - GitHub: https://github.com/idavidov13 ❤️ Support my work: https://buymeacoffee.com/idavidov 📺 Full TypeScript for Automation QA playlist: https://www.youtube.com/playlist?list=PLYxABk1YARBwGAnMRlwJCt-TZ8rjbjh48 - Previous: First Steps in TypeScript — [YouTube URL TBD] - Next: Fundamental Logic — [YouTube URL TBD] #playwright #typescript #framework #qa #softwaredevelopment #softwaretesting #api #ui #testing #quality #qualityassurance #testautomation #engineering
