Tempo: An Easier Way to Work with Dates — We think they nailed their own summary: “A collection of utilities for working with the native Date object — an important distinction from other libraries that provide custom date primitives. Under the hood, Tempo mines Intl.DateTimeFormat to extract complex data like timezones offsets and locale aware date formats, giving you a simple API to format, parse, and manipulate dates.” Fantastic docs, too.

LLRT (Low Latency Runtime): Amazon’s New JS Runtime — Amazon has open sourced a runtime entirely focused on fast startups – something that’s useful for ephemeral use cases like serverless (*cough* AWS Lambda). It uses Fabrice Bellard’s QuickJS as the underlying engine, so has almost full ES2023 spec support out of the box.
