Example function funstuff_system in "Function Declarations" section was having comma after last parameter that is not valid. The comma is removed.

In case function argument, there must not be comma (,) after last parameter whether it is on the same line with other arguments or on separate line. So this line is not required:

• The last argument in the list must use a trailing comma.

This is not the array items where if the array imets listed on separate line then there shuld be comma after last item.

Method name getCourses() was not correct or matching withe functionality. Changes to getPostComments().

getLimit() method was duplicate while it should be getSort() method.
