@typescript/twoslash

npm · v3.2.13 · MIT

A markup format for TypeScript code, ideal for creating self-contained code samples which let the TypeScript compiler do the extra leg-work. Inspired by the [fourslash test system](https://github.com/orta/typescript-notes/blob/master/systems/testing/fours

Tentative categories were assigned with moderate confidence (0.5 to 0.75): they are shown, but they do not count toward a category’s momentum. How categories work
