is there a possibility to call user path from javascript

I have an HTTP request for which the response is received as JSON array. Iterate through each JSON object and based on the attribute in JSON different execution path has to be followed. Ex: if attr = p; Flow 1 has to be called and if attr = f; Flow 2 has to be called.
Is there a possibility to call user path from javascript because iterating the JSON array is done in javascript only.
