Over the past year or so, something unexpected happened: TypeScript has seemingly become my most used scripting language, thanks in no small part to Deno. There are quite a few reasons for this: It’s well suited for my recent scripting needs which involved a lot of ETL tasks with CSV and JSON files, as well as REST APIs as data sources. I also had to write quite a few data migrations for a Firestore database, another area where TypeScript seemed like a good choice.
