JSON.parse() can be used to parse a given json string into javascript value (array, string, etc.)
Here are some examples
Example – parse json containing string
<pre></pre>
<script>
var v = '"str1"';
jsVal = JSON.parse(v);
document.querySelector("pre").innerText = typeof(jsVal);
</script>Example – parse json containing array
<pre></pre>
<script>
var v = '["val1", "val2", "val3"]';
jsVal = JSON.parse(v);
document.querySelector("pre").innerText = typeof(jsVal) + " jsVal[0]=" + jsVal[0];
</script>Example – parse json containing object
<pre></pre>
<script>
var v = '{ "x": "val1", "y": "val2", "z": "val3"}';
jsVal = JSON.parse(v);
document.querySelector("pre").innerText = typeof(jsVal) + ' jsVal["x"]=' + jsVal["x"];
</script>
