title: Redis + Node.js - how do I retrieve the values
body: <p>I am using a Redis database with Node.js.
  Using 
  <code>client.hmset("jobs", "jobId_12345", JSON.stringify(jsonJob))</code>
  I store JSON stringified jobs.</p>
  
  <p>Now I want to iterate over all jobs and retrieve both job id and stringified job.</p>
  
  <p>I tried 
  <code>client.hkeys("jobs", function (err, replies) {}</code>
  but that only retrieves the keys.</p>
  
  <p>I tried 
  <code>client.hgetall("jobs", function (err, obj) {}</code>
  but I don't know how to retrieve both key and value from obj.</p>
  
  <p>Any help is greatly appreciated because I'm stuck.</p>
