enum is a keyword that allows you to declare an enumeration. an enumeration is a set of names for valeus. for example
enum Dificulty {easy,normal,hard};
then you can declare variables of type Dificulty and set it's value as easy/normal/hard
Dificulty d = Dificulty.easy;
enums make your program more readable and help you to don't set integer values incorrectly. remembering easy is easier than remembering 0 or 1. a complete reference is available on MSDN [here.][1]
as you can read there the value is easy is 0 and normal 1 and hard 2. values are increased by one and you can set the values to numbers that you want. the type is a constant integral type. by constant i mean that you can not change the value of Dificulty.easy after defining the enum.
unity uses enums for sending constant values to functions. you can see enums usefulness from Input.GetMouseButton() i always froget what number is for what button but if it had an enum like
enum MouseButton {left,middle,right};
then it was easy to set this just like KeyCode and other available enums.
using enums in javascript is the same but i don't know how to define them in js.
hope this helps.
