The Temporal proposal offers a new API to replace the problematic Date object in JavaScript. Temporal reached Stage 3 of the TC39 process in March 2021, signifying it was ready for implementation. André Bargull, a volunteer, significantly contributed to its implementation in SpiderMonkey, with Firefox 139 being the first browser to enable it by default. The project highlights the positive impact of volunteer contributions in open source.
