Dates and Times in JavaScript
tl;dr: We are looking for feedback on the Temporal proposal. Try out the polyfill, and complete the survey; but don't use it in production yet! JavaScript Date is broken in ways that cannot be fixed without breaking the web. As the story goes, it was included in the original 10-day JavaScript engine hack and based on java.util.Date, which itself was deprecated in 1997 due to being a terrible API a

Show navigation All episodes In this episode, we’ll go deeper in the definition of the ECMAScript language and its syntax. If you’re not familiar with context-free grammars, now is a good time to check out the basics, since the spec uses context-free grammars to define the language. See the chapter about context free grammars in "Crafting Interpreters" for an approachable introduction or the Wikip

Learning CSS by reading specs
Recently I got the chance to do an interview with Vitaly Friedman as part of the run-up to View Source Conference taking place in September this year. One of the things we chatted about was around new CSS. My good friend, Wei, is an incredible technical writer who is very involved in documentation for open-source projects. She wrote most of the React-Redux documentation and is one of the core main

What’s New in HTML 5.2? | bitsofcode
Less than a month ago, HTML 5.2 became an official W3C Recommendation (REC). When a specification reaches the REC stage, this means that it has received the official endorsement of W3C Members and the Director, and that the W3C officially recommends it’s deployment by user agents, and it’s implementation by web page authors. By the REC stage, anything new should have had at least 2 independent imp
