Speeding up the JavaScript ecosystem – module resolution

This excellent article taught me how module resolution works behind the scenes (i.e., how Node.js can import without file extensions). Check out the author’s first article on Javascript performance, too.

The gotcha of unhandled promise rejections

I am used to seeing a few warnings about unhandled promises during development and testing. But I never wondered what “unhandled” really meant. The article explains how they happen and how we can work around some tricky scenarios.

Announcing TypeScript 5.0 Beta

Another version of Typescript is coming out. If you are familiar with SemVer, it may look like a major release, but it’s not. Typescript does not follow SemVer and goes from x.9 to x+1.0, with every release having a few breaking changes. I am most looking forward to the improved module resolution in this release.

This Linux Foundation project defines many metrics to measure the health of an open-source project and maintains a tool to measure them. Given that our technology choices have a long-term impact (imagine you chose Angular instead of React five years ago), it’s prudent to understand the community health of the technologies.

I got quite a bit pessimistic about these devices after reading this.


Consumer Reports, a US non-profit, created an automation app for consumers to protect their data based on the California Consumer Privacy Act.

Apparently, many staged photos on real estate listings are now “virtually staged,” meaning that the furniture and fixtures are photoshopped. It disturbs me to think that we won’t be able to trust information about the most expensive purchases of our lives.
