To count the number of objects in object literal using Jquery

javascript, jquery, jquery-ui, object, object-literal

Solution

You could use `Object.keys(animals).length`

Or

var count = 0;
for (var animal in animals) {
    if (animals.hasOwnProperty(animal)) {
        count++;
    }
}
// `count` now holds the number of object literals in the `animals` variable

Or one of many jQuery solutions that may or may not be the most efficient:

var count = $.map(animals, function(n, i) { return i; }).length;

Problem

Code: ``` var animals = { "elephant": { "name" : "Bingo", "age" : "4" }, "Lion": { "name" : "Tango", "age" : "8" }, "Tiger": { "name" : "Zango", "age" : "7" } } ``` I want to count the number of objects using Jquery in this object literal.
