How do get only first value from JSON object

I am having JSON Object in ajax response like that. I have to show these message on UI , for this I am using linke that .msg.result.word_containing_more_than_avg_chars It will works fine . But the problem is key is dynamic, in some case keyword_containing_more_than_avg_chars becomes title_containing_more_than_avg_Words . SO how do handle all case in such that I can get value part only irrespective of key .

Below code is more efficient,

Object.values(msg.result)[0];

<html>
<head>
</head>
<body>
<div id="container"></div>

<script>

testobj = {"a" : "123", "b" : "234"};
testArray = [];
for (key in testobj) {
    testArray.push(testobj[key]);
}
document.getElementById('container').innerHTML = testArray[0];

</script>
</body>
</html>

I thought that I would answer this in a more generic way.

I saw it a little less efficient than the answer that is already here, however I personally iterate through them using a for loop, because it seems that at least in Chrome there was not an appropriate method for keys on the Object.

Get the key using Object.keys method which returns an array of object property names.

msg.result[Object.keys(msg.result)[0]]
