Javascript: get length returns undefined

Question

Below are the links I gone through:
1. Javascript : array.length returns undefined
2. Javascript Array.length returns 0
3. array.length returns undefined if the last element is undefined in javascript

Code:

<script type="text/javascript">
    var freelancer = <?php echo json_encode($results); ?>;

    console.log(freelancer);  // freelancers: Array(19)
    console.log(freelancer.length); // undefined
    console.log(Object.keys(freelancer).length);  // 1
</script>   

Console Log:

Now how can I get the exact length of the array?

Answer 1

var freelancer = <?php echo json_encode($results); ?>;

is an object with a property freelancers in it.

Use

freelancer.freelancers.length

to access the array.
