Return a boolean dependant upon the specified object having been created as a Function JavaScript object.
In the example below when we press the button we create some variables and test to see if they are Function JavaScript objects.
$(function(){
$('#btn4').one('click', function(){
var obj1 = 'aaa', obj2 = new Function('a', 'return a * a'), obj3 = {}, obj4 = new Object;
$('#div4').append('Is obj1 a function? ' + $.isFunction(obj1) + '<br>');
$('#div4').append('Is obj2 a function? ' + $.isFunction(obj2) + '<br>');
$('#div4').append('Is obj3 a function? ' + $.isFunction(obj3) + '<br>');
$('#div4').append('Is obj4 a function? ' + $.isFunction(obj4) + '<br>');
