title: Adding data to existing object mapping a contanst key/value
body: <p>In my first function, I am getting a few pieces of information and pushing them to my object.</p>
  
  <pre><code>  autoArry.push({
          id: countTxns,
          txnID: txnID,
          account: buyersAccount,
          data1: '',
          data2: '',
          data3: ''
      });
  </code></pre>
  
  <p>At this point, I dont have the information from data1, data2, or data3 but I created them in the object anyway.</p>
  
  <p>Later in my script, I want to be able to fill in those data values when i collect it throughout other functions.</p>
  
  <p>The one thing that I will have that is the same in every function is the txnID.</p>
  
  <p>I assume I will have to Map that somehow and then add additional data that way.</p>
  
  <p>Would anyone be able to explain how I could do this?</p>
  
  <p>Thanks Much</p>
