It&#x27;s not in any way a physical limitation that Dart is slower than Java. It&#x27;s just somewhat harder to make fast, and even then, some of Dart&#x27;s design is motivated by being able to implement the language efficiently. [1]<p>Dart could even in theory have a compiler that assumes all your type annotations are correct and simply AOT compiles your code. (So your workflow would be: develop -&gt; fix type errors -&gt; run in regular VM -&gt; loop -&gt; AOT compile -&gt; deploy.) Whether that would be useful is another matter, but it could certainly be possible (some Common Lisp implementations in fact do exactly this [2]).<p>--<p>1: <a href="https:&#x2F;&#x2F;www.dartlang.org&#x2F;support&#x2F;faq.html#q-why-dart" rel="nofollow">https:&#x2F;&#x2F;www.dartlang.org&#x2F;support&#x2F;faq.html#q-why-dart</a><p>2: <a href="http:&#x2F;&#x2F;www.sbcl.org&#x2F;1.0&#x2F;manual&#x2F;Declarations-as-Assertions.html" rel="nofollow">http:&#x2F;&#x2F;www.sbcl.org&#x2F;1.0&#x2F;manual&#x2F;Declarations-as-Assertions.ht...</a>
