+# js2
+
+This directory contains Deno runtime code written in plain JavaScript.
+
+Each file is a plain, old **script**, not ES modules. The reason is that
+snapshotting ES modules is much harder, especially if one needs to manipulate
+global scope (like in case of Deno).
+
+Each file is prefixed with a number, telling in which order scripts should be
+loaded into V8 isolate. This is temporary solution and we're striving not to
+require specific order (though it's not 100% obvious if that's feasible).
