How to sort json object?

I've been looking for a while and want a way to sort a JSON object like this:

{"results": [ { "layerId": 5, "layerName": "Pharmaceutical Entities", "attributes": { "OBJECTID": "35", "FACILITYTYPE": "Pharmacy", "FACILITYSUBTYPE": "24 Hr Pharmacy", "COMMERCIALNAME_E": "SADD MAARAB PHARMACY", }, "geometryType": "esriGeometryPoint", }, { "layerId": 5, "layerName": "Pharmaceutical Entities", "attributes": { "OBJECTID": "1", "FACILITYTYPE": "Pharmacy", "FACILITYSUBTYPE": "24 Hr Pharmacy", "COMMERCIALNAME_E": "GAYATHY HOSPITAL PHARMACY",

},
"geometryType": "esriGeometryPoint",

}, { "layerId": 5, "layerName": "Pharmaceutical Entities", "attributes": { "OBJECTID": "255", "FACILITYTYPE": "Pharmacy", "FACILITYSUBTYPE": "24 Hr Pharmacy", "COMMERCIALNAME_E": "AL DEWAN PHARMACY", }, "geometryType": "esriGeometryPoint", } ]}

and sort is alphabetically by value of "COMMERCIALNAME_E" to get:

{"results": [ { "layerId": 5, "layerName": "Pharmaceutical Entities", "attributes": { "OBJECTID": "255", "FACILITYTYPE": "Pharmacy", "FACILITYSUBTYPE": "24 Hr Pharmacy", "COMMERCIALNAME_E": "AL DEWAN PHARMACY", }, "geometryType": "esriGeometryPoint", }, { "layerId": 5, "layerName": "Pharmaceutical Entities", "attributes": { "OBJECTID": "1", "FACILITYTYPE": "Pharmacy", "FACILITYSUBTYPE": "24 Hr Pharmacy", "COMMERCIALNAME_E": "GAYATHY HOSPITAL PHARMACY", }, "geometryType": "esriGeometryPoint", }, { "layerId": 5, "layerName": "Pharmaceutical Entities", "attributes": { "OBJECTID": "35", "FACILITYTYPE": "Pharmacy", "FACILITYSUBTYPE": "24 Hr Pharmacy", "COMMERCIALNAME_E": "SADD MAARAB PHARMACY", }, "geometryType": "esriGeometryPoint", } ]}

I can't find any code that will do this. Can anyone give me some help? Please give me any sample code to do solve this scenario.
