Most team training budgets go like this: buy 25 seats in January, use 11 by December. We built our credit system the other way around. 🧠 We're piloting this with 5 engineering teams. If you manage L&D or a dev team budget, we'd like to hear from you!

The TypeScript Mid exam is 135 minutes. 40 multiple-choice questions, then 105 minutes of real coding. Passing it means you can produce types, not only consume them. Martin Ferret built the exams, and these are the three areas he'd prepare first 🧵

The edge of your program 🚪 External data starts as unknown and gets validated at runtime. You'll also type promises, generators and errors, including why a caught error is unknown.

Only have one evening? Spend it on the mock exam. It’s a short version of the real exam (10 questions and one coding challenge), so you’ll see where you’d pass today and where you wouldn’t yet. Doors open Fri 13 Nov at 22:00 CET!
