<p>This shows how much time total it takes to run a few simple deno programs:</p>

</a>
</p>
<p>
For deno to execute typescript, it must first compile it to JS. A warm
startup is when deno has a cached JS output already, so it should be fast
because it bypasses the TS compiler. A cold startup is when deno must
compile from scratch.
