An impressive virtual machine emulating a 1991 Macintosh Quadra 900 with System 8, all running in Electron. We linked to this several years ago but it’s had some updates since then and runs faster than before. As well as a few games, such as Oregon Trail, there are a variety of apps pre-installed, including a trial of Adobe Photoshop 3 which starts up faster than my real Photoshop now.. (Download necessary since it's an Electron app and all..)

📄 My Experience Modernizing Packages to ESM
What a post! Mark, well known for his work on React, Redux, and much more, details the painful experiences and hard-earned lessons he picked up while migrating the Redux packages to ES modules.
MARK 'ACEMARKE' ERIKSON
📄 Things You Forgot (or Never Knew) Because of React
“I’ve written before about how React is the new default frontend framework, and how I don’t think most people using React on a regular basis realize quite how much it’s fallen behind.” High level thoughts about the React ‘bubble’ and some reasons to look beyond it, including a round up of some of the alternative options.

Calculate the real ‘cost’ to run your JS app or lib and maintain an eye on performance and raise the alarm (in your CI system, say) when things go awry. Supports ES modules and tree shaking.

An intriguing project where you ‘draw’ diagrams in plain ASCII text within special
script tags and these get rendered into much nicer looking versions. An interesting approach if Mermaid is too full on for your needs.SAM GOTO / GOOGLE

This is more powerful than I was expecting. You can basically record a screencast using browser APIs. In Chrome, at least.
