We asked members of the JavaScript community to share their “pick of the year”

My 2023 Pick: Electron

With everyday apps like VS Code, Figma, Discord, Slack and 1Password all running on Electron, it remains an integral part of the JS and developer ecosystem. Many tools we all use wouldn't exist without it, and when used correctly it's a powerful platform indeed.

My 2023 Pick: Web Interoperable Runtimes

Web Interoperable Runtimes are execution environments that allow code to run consistently across multiple platforms and environments. I believe that working with such a standard exposes us to the future of web development.
