How to know the total number elements present in an array?

How to know the total number elements present in an array?

We can use sizeof() method and length.

For example you can seen below.


    // define an object for sizeof().
    var sofObject =
        {
            'boolean': true,
            'number': 1,
            'array': [1, 2, 3]
        };

    // Get the size of the "sofObject" object.

    var size = sizeof(sofObject);

    //OR

    var object = [];

    var size = object.length;
