ts-koans

ts-koans

Inspired by Elixir Koans, ts-koans is an interactive way to learn about TypeScript's type system, from the basic to the complex.

Prerequisites

• Node.js >= 20
• TypeScript

Note that if you use a version manager such as nvm, n, asdf or mise, your tsc installation might not be globally available. Please make sure they're in your $PATH before running ts-koans.

Installing from npm (either globally or locally) will download tsc and make it available, so running ts-koans will use the one installed by npm, if available.

Running

NPM

npm i -g ts-koans

and then

ts-koans

GitHub Release

Download the latest release for your architecture, then extract and run tskoans from your favorite terminal emulator.

From Source

Alternatively, you may clone this repo and run go run . from the root. This requires golang to be available in your $PATH.

Problems?

Please open an issue if you encounter any errors! This is still very early in development. It is not "battle-tested" or "hardened." In fact it is quite soft and pleasantly squishy.

Contributing

What, you think you can make it better? You probably can! I'm not a golang expert, or a typescript expert, or an expert in many other things. If you want to open a PR with some enhancements, I will do my best to review it (but I make no promises).
