title: Changing the case of JavaScript object keys
body: <p>I have following object.</p>
  
  <pre><code>var obj = [{
    Address1: "dd",
    Address2: "qww",
    BankAccNo: "44",
    BankBranchCode: "44",
    BloodGrp: "A+"
  },
  {
    Address1: "dd",
    Address2: "qww",
    BankAccNo: "44",
    BankBranchCode: "44",
    BloodGrp: "A+"
  }];
  </code></pre>
  
  <p>How can I make all of the keys uppercase?</p>
  
  <p>I want to be able to access values like this : - <code>obj[0].ADDRESS1</code></p>
