Accessing Enum Values

TypeScript map objects to allow access

A variable set with an enum that has a number lets you access the enum name from the integer. However, an enum with string values does not have this capability. This means you can use the enum name followed by the name of the constant to get the value. Also, with a number, you can also use the value to return the name.

For example, an enum called Orientation with East, West, North, South could use Orientation.East to get the value zero or use Orientation[0] to get East. This works because TypeScript generates a map object which gives you access using the name of the entry or the value.
