{% codeblock classobj/get_declared_classes.js lang:js https://raw.github.com/kvz/phpjs/master/functions/classobj/get_declared_classes.js raw on github %}
function get_declared_classes () {
  // http://kevin.vanzonneveld.net
  // +   original by: Brett Zamir (http://brett-zamir.me)
  // +    depends on: class_exists
  // *     example 1: function A (z) {this.z=z} // Assign 'this' in constructor, making it class-like
  // *     example 1: function B () {}
  // *     example 1: B.c = function () {}; // Add a static method, making it class-like
  // *     example 1: function C () {}
  // *     example 1: C.prototype.z = function () {}; // Add to prototype, making it behave as a "class"
  // *     example 1: get_declared_classes()
  // *     returns 1: [C, B, A]

### Example 1
This code
{% codeblock lang:js example %}
function A (z) {this.z=z} // Assign 'this' in constructor, making it class-like
function B () {}
B.c = function () {}; // Add a static method, making it class-like
function C () {}
C.prototype.z = function () {}; // Add to prototype, making it behave as a "class"
get_declared_classes()
{% endcodeblock %}

Should return
{% codeblock lang:js returns %}
[C, B, A]
{% endcodeblock %}
