I liked Dart from the beginning... It could have been a perfect replacement for JavaScript a few years ago, but now with ES6 becoming widely available in browsers and Node.js, I feel that some of the shine of Dart has been lost.<p>I think the biggest problem with Dart isn&#x27;t related to the project itself - My biggest concern is that other browser vendors didn&#x27;t embrace it. Dart has not been universally accepted by all sides, despite the massive amount of publicity which it received over the years.<p>With ES6, I think that JavaScript has proved that it can adapt to change and that it has significant staying power.<p>I think the Dart team made all the right moves, but, unfortunately, so did the JS team.<p>The project hasn&#x27;t had much luck either. There was no breakthrough. Getting its own native VM inside Chrome would have been nice.
