Most of these come from public snippet collections and are reproduced here so they can be searched with the rest of the wiki. Each one is a short example, not a library: none validates its input, handles errors or considers allocation in a hot path, and none ships with tests. Read the explanation and the edge cases before copying one, then add the validation and tests your code needs. For language guidance see [Go](https://www.wiki.jodisand.me/go/), [Python](https://www.wiki.jodisand.me/python/) and [TypeScript](https://www.wiki.jodisand.me/typescript/).
