JavaScript - How can I iterate object that is actually a map?

Question

I got a JSON object from the server that is actually:

Map<Integer, Integer>

How can I iterate over it and get the key and value in each iteration?

Thanks!

Answer 1

Just like that:

var key, response = {1:3, 5:6, 3:8}; // sample response of your server
for (key in response) {
    if (response.hasOwnProperty(key)) {
        console.log("key: " + key + ", value: " + response[key]);
    }
}

Output:

key: 1, value: 3
key: 3, value: 8
key: 5, value: 6

Answer 2

Once you convert the JSON string to an object you can use a foreach style for loop

for ( var key in map){
  var value = map [key];
  ....
}
