+// Module "timer"
+//
+// This module provides basic createOneShot, createRepeating support. The
+// reason to define this module is to forward calls to setTimeout, setInterval
+// exposed by the browser. Mojo JS bindings are currently loaded using gin
+// and createOneShot, createRepeating is not always available.

Done.

+//
+// TODO(crbug.com/703380): When the Mojo JS bindings move away from gin,
+// this module could be removed.
