I doubt it.<p>&gt;<i>And then I can build a compliant JavaScript implementation on top of this, in order to be able to parasite on 200k npm packages (actually, did this already).</i><p>Link or it didn&#x27;t happen.<p>Besides, there&#x27;s no point in using Forth if you&#x27;re gonna end up running your stuff in a &quot;compliant JavaScript implementation&quot; (which takes much more than &quot;several days&quot; anyway).
