+# goja function

+`goja()` creates a JavaScript VM that receives and sends data through the defined javascript function for processing. The parameter passed to the function has been converted from a go map[string]interface{} to a JS object of the following form:

+```JSON
+{
+    "ns":"message.namespace",
+    "ts":12345, // time represented in milliseconds since epoch
+    "op":"insert",
