Check if a variable is an array
Description
.isArray() checks whether an object is an array.
You can turn an array-like object to a true array using .makeArray().
By converting an array-like object to an array, you lose its methods and properties.
Example
<!DOCTYPE html>
<html>
<head>
<script src="http://yourServer.com/jQuery/jquery.min.js"></script>
<script>
// clone jQuery object
var clonedjq = $.extend(true, {}, $);
//returns "object"
console.log($.type(clonedjq));
<!-- w w w.j a v a2 s .c o m-->
// convert to JS array
var jqArray = $.makeArray(clonedjq);
// returns "array"
console.log($.type(jqArray));
</script>
