The recent TC39 meeting in Tokyo brought some great updates that will make working with JavaScript even better. JavaScript features go through six different "stages" before becoming available, and here are some highlights: Iterator Helpers just reached stage 4, allowing for more efficient data handling; Promise.try, now in stage 4, simplifies error handling in promises; and Math.sumPrecise alongside Shared Structs are aimed at enhancing overall efficiency.
Deno 2 just dropped, and it's packed with new features! Built to simplify JavaScript and TypeScript development, Deno 2 is backward compatible with Node.js, allowing for seamless integration of existing Node projects. Key features include a 90% faster package manager thanks to a hot cache and enhancements for managing large projects, making Deno an attractive choice for developers.
TypeScript 5.7 Beta has landed, bringing with it some helpful updates, including a vigorous new check for never-initialized variables to catch bugs early and path rewrites for relative imports which simplify the codebase. With TypeScript 5.7 reaching near feature-stability, users can anticipate significant bug fixes and improvements in performance in the final release.
