title: JavaScript in Zapier - Incorrect behavior of "IF" statement
body: <p>I have a JS Task from Zapier that does some logic over the incoming data.</p>
  
  <pre><code>//if club member or joining - update points
  var club = 0;
  var points = 0;
  
  if(inputData.existingMember || inputData.joiningClub == 'Yes') { 
      var club = 1; 
      var points = existingPoints+parseInt(inputData.amount,10)*0.1; 
  }
  </code></pre>
  
  <p>I had "inputData.existingMember" as 0
  and "inputData.joiningClub" as "No" </p>
  
  <p>The if resulted as true and I had club=1 as a result.</p>
  
  <p>I tested the script in a sandbox and it shouldn't go through. What's going on? I have no way of debugging it and don't know how is this happening.</p>
