Node.js: Performance Wins and Crypto Cleanup
Today brings some fantastic performance improvements to Node.js, with major optimizations to event emitters and crypto operations. Seven pull requests were merged, including a clever EventEmitter optimization that avoids unnecessary array cloning and a crypto enhancement that more than doubles EC JWK import performance. The team also tackled some important housekeeping with deprecations and test reliability fixes.

Hey there, Node developers! Welcome back to another episode of the Node.js podcast. I'm your host, and wow, do we have some exciting updates to dive into today. March 30th brought us seven solid pull requests that really showcase the community's commitment to making Node faster, more reliable, and cleaner under the…
Let's start with the star of today's show - a brilliant performance optimization to Node's EventEmitter system. Gürgün Dayıoğlu submitted a pull request that tackles something we've probably all taken for granted: how event listeners get handled when you emit events. Here's the clever part - instead of cloning the…
Speaking of performance wins, Filip Skokan delivered another knockout punch in the crypto department. If you're working with elliptic curve JWK imports - and honestly, who isn't dealing with crypto keys these days - you're going to love this. The optimization more than doubles performance, jumping from about 76,000…
Now, Filip wasn't done there. He also tackled some important housekeeping by runtime-deprecating two crypto deprecations - DEP0203 and DEP0204. I know deprecations aren't the most exciting topic, but they're crucial for keeping the platform moving…
