How do I access nested objects in JavaScript?

Access with index to position in JSON Array

var a = [{"ID":102254,"Name":"obj 1","service_name":["Open  Ticket","Escalation Ticket"]},{"ID":226619,"Name":"DIDE","service_name":["Open  Ticket","Escalation Ticket"]},{"ID":224522,"Name":"CAT","service_name":["Open  Ticket","Escalation Ticket"]},{"ID":122533,"Name":"Mirror","service_name":["Open  Ticket","Escalation Ticket"]}] 
 
 
console.log(JSON.stringify(a[3].service_name[0])) 
<!-- "Open Ticket" will be displayed -->
