TypeScript Accelerated

TypeScript Accelerated is a flash card App for learning the TypeScript programming language.
When you have a few free minutes you can go through a batch of flash cards. If you don't understand something you can jump to an explanation of that topic.
The App tracks your how well you know each card individually and prioritises drilling you on those you are struggling with, while occasionally checking those you know well.
It brings techniques from (natural) language learning to learning programming languages and aims to make you truly fluent at TypeScript.
