Child element count returns 'Undefined' in jQuery

Asked

I am trying to count child elements of a parent element with jQuery in the HTML I created, but it is returning the value 'Undefined'.

<div class='dataGrid'>
    <div class='dataGrid-item'></div>
    <div class='dataGrid-item'></div>
    <div class='dataGrid-item'></div>
    <div class='dataGrid-item'></div>
    <div class='dataGrid-item'></div>
    <div class='dataGrid-item'></div>
</div>

And the jQuery I incremented was.

<script>
    $(document).ready({
        var qtdGrid = $('div.dataGrid div.dataGrid-item').lenght;
        window.alert(qtdGrid);
    });
</script>

In the console no error is returned, only in the 'Undefined' Alert'.

You put lenght instead of length

/// var qtdGrid = $('div.dataGrid div.dataGrid-item').lenght;
///                                                     ^

console.log( [1,2,3,4].length );
///                      ^ exemplo
