A task, its code, run
How to
The library's recipes: each answers one "how do I…?" with one block of code. Every recipe was run inside the library before it was published; its output is that run's.
Recipes read in the library's doc/quickers/recipes folder at commit 0e72e2e2c and run on 2026-10-02 22:33, all in one process. An expression that carries a promise without printing it was printed for the run.
