  1. I got the data json using XMLHttpRequest('get','data.json',true) and stored in jsonData
    converted it into javascript object
    jsObj = JSON.parse(jsonData)
    I log id and got
    addresses:

    city: "New York"

    postalCode: "10021-3000"

    state: "NY"

    streetAddress: "21 2nd Street"

    __proto__: Object

    age: 25

    children: Array(0)

    length: 0

    __proto__: Array(0)

    firstName: "John"

    isAlive: true

    lastName: "Smith"

    phoneNumbers: Array(2)

    0:

    number: "212 555-1234"

    type: "home"

    __proto__: Object

    1:

    number: "645 555-4567"

    type: "office"

    __proto__: Object

    length: 2

    __proto__: Array(0)

    spouce: null

    —————————————————–
    In the browsers console it shows
    jsObj.phoneNumbers is an Array
    but when I ask wether it is an array or not it says it is an ojb
    console.log(typeof(jsObj.phoneNumber)) //ouput: Object
    console.log(typeof(jsObect.phoneNumber ==='array')) //output: false

    Can someone explain why this happens?
    The data is the same as the tutorial used here, just by another name 🙂

  3. I get openweather JSON array in it's callback function – 'test'. How do I retrieve from here, as the javascript obj.weather.description seems to fail.

    Here is what I receive –
    test({"coord":{"lon":72.85,"lat":19.01},"weather":[{"id":721,"main":"Haze","description":"haze","icon":"50d"}],"base":"stations","main":{"temp":32.11,"pressure":1008,"humidity":79,"temp_min":31,"temp_max":33},"visibility":2500,"wind":{"speed":2.1,"deg":220},"clouds":{"all":75},"dt":1508137200,"sys":{"type":1,"id":7761,"message":0.0051,"country":"IN","sunrise":1508115784,"sunset":1508157890},"id":1275339,"name":"Mumbai","cod":200})

    (notice the test() around)

  5. Let's say that I want to retrieve data from a JSON file because I don't want JSON format on my JS file, how do I retrieve the data?

    Good tutorial BTW!
