iterating through JSON object with javascript -

in example, extract 1) employee number , 2) of her/his tasks. 2) works, 1) gives me object not number...

do have set employee number key/value pair able extract value?

var s = {     "schedule": {         "employees": {             "1000": {                 "tasks": [                     {                         "task": "task1",                         "site": "site1",                         "from": "0900",                         "to": "1000"                     },                     {                         "task": "task2",                         "site": "site2",                         "from": "0900",                         "to": "1000"                     }                 ]             },             "2000": {                 "tasks": [                     {                         "task": "task3",                         "site": "site3",                         "from": "0900",                         "to": "1000"                     },                     {                         "task": "task4",                         "site": "site4",                         "from": "0900",                         "to": "1000"                     }                 ]             }         }     } }  (var in s["schedule"]["employees"]) {     // gives me object, employee number (eg:1000)     console.log(s["schedule"]["employees"][i]);      // gives me task number      (var j in s["schedule"]["employees"][i].tasks) {         console.log(s["schedule"]["employees"][i].tasks[j].task);            } } 

i don't know why having trouble understanding this. one?

just use i view key.

console.log(i);
