I develop with both, and Dart wins hands-down. ES6&#x2F;TS adds a lot of Dart&#x27;s best features to JavaScript, but without getting rid of JS&#x27;s annoying problems. Many here have mentioned that Dart&#x27;s standard library is among the best there is, and that&#x27;s no exaggeration. That alone makes it better.<p>Whenever I have a choice, I always use Dart. The tools (analyzer, profiler, etc.) automatically make me twice as productive as when I use JS.
