Javascript provide JSON.parse(); for parsing json data.

You can save your response in variable.

var response=JSON.parse(data);

Then use the all value from it's key.

var name = response.devices[0].name;
var host = response.devices[0].host;
var target = response.devices[0].target;

These code only get the 1st array element values. Using for loop you can get get all values from devices array.

var data = JSON.parse(response);

data.devices.forEach(function(device) {
    if(device.name === 'iPhone 4s') {
        console.log(device.name, device.host, device.target);
    }
});

// 'iPhone 4s', '3.175: 375', '137fc82506eb75431ec96fdd'
