✌️ Shiki 1.0: A Powerful Syntax Highlighter

A few months ago, we linked to Shikiji, a fork of Shiki that was created to push the project forward. Happily, the creators of both libraries decided to join forces and Shiki 1.0 was born.

I don't know why I’ve not linked this before, as it’s so useful. Playwright isn’t just a library for controlling browsers from JavaScript, but also includes a tool for generating tests and page navigation code from your own interactions. Hit record, do stuff, and code is written.
