add array key to values js code example
Example 1: how to add field to object in js
// original object { key1: "a", key2: "b"}
var obj = {
key1: "a",
key2: "b"
};
// adding new filed - you can use 2 ways
obj.key3 = "c"; // static
// or
obj["key3"] = "c"; // dynamic - 'key3' can be a variable
console.log(obj) // {key1: "a", key2: "b", key3: "c" }

var myArray = {id1: 100, id2: 200, "tag with spaces": 300};
myArray.id3 = 400;
myArray["id4"] = 500;
for (var key in myArray) {
console.log("key " + key + " has value " + myArray[key]);
}
