<pre>Modern JavaScript APIs are growing more and more Promise heavy. It would be awesome if the benchmark suite was enhanced to cover Promise performance.
One option would be to add a dedicated Promise benchmark. Alternatively the pdfjs bench could be updated to use the javascript engine's built-in Promise when available.
