🌲 Node.js 22.0 (Current) Released The latest major version of Node is here. Note that it’s a ‘Current’ release for now, so gets all the newest features first, but is due to become Node's main active LTS release this October. As an even numbered release, Node 22 should be around and maintained for a long time, most likely out to 2027 or so (see image above).

❓ CHALLENGE

console.log('Start');

setTimeout(() => {
  console.log('Timeout 1');
  Promise.resolve().then(() => console.log('Promise 1'));
}, 0);

Promise.resolve().then(() => {
  console.log('Promise 2');
  setTimeout(() => console.log('Timeout 2'), 0);
});

console.log('End');

🤔 JSR is Not Another Package Manager When Ryan created Node, JavaScript had no packages or standard module system. npm and CommonJS took off, and tools like Yarn or pnpm extended npm in certain areas, but in today's ES modules era, it’s time for a transformation. JSR is not merely a new npm, but a shift in how packages are distributed, tailored for the modern era. RYAN DAHL
