React 'Aha' Moments
One of my main goals, whenever I'm teaching or writing technical content, is to maximize "aha" moments. An "aha" moment is a moment of sudden insight or clarity; when the subject matter suddenly makes sense. We've all experienced them, and the best teachers I know can understand their audience and adapt the lesson to maximize these moments. Throughout the last few years, I've taught React in just

TC39: Promises, Promises
This week's meeting has a few different Promise-related spec changes. Promise.try: async function as a Library One of the goals of Promise APIs is that exceptions that happen while processing the request become Promise rejections, rather than bubbling up to the top level (e.g. window.onerror).
