🤔 The Roadmap to AdonisJS 7
Adonis is a popular TypeScript-first 'batteries included' web framework with a rich set of features, and its developers say they’re “shifting gears” and stepping up with more frequent major releases. v7 promises a lot, including Node.js diagnostic channel support, a type-safe URL builder, a new encryption layer, first-class support for notifications and TanStack Query, plus more. You’re encouraged to give your feedback here.

📖 Exploring JavaScript (ES2025 Edition)
Dr. Axel is back with his latest book covering all things relating to modern JavaScript at the language level (think built-in data types, modularity, how objects, classes and promises work, etc.). As with all of Axel's books, it’s available to buy but also to read online in HTML form for free. He’s also produced a set of flashcards to help you learn language features in both HTML and Anki forms.
