JSON is a string. "JSON Array" is not a thing. What you have is an array of objects, that you want to convert to an array based on a property of those objects. –  Niet the Dark Absol 15 hours ago
    
What's the problem? You don't know how to use a for loop? or you don't know how to add items to a new Array? –  cookie monster 15 hours ago

I'd use Array.prototype.map:

var new_array = arr.map(function(e) {
    return e.sw;
});

Don't forget to get the actual JavaScript array from the JSON string with JSON.parse (as an example).

Try this:

var convertedArray = JSON.parse(jsonArray);

This doesn't appear to perform what was specified in the question. It just parses it, but it doesn't transform the object into an array of strings. –  OneKitten 14 hours ago
