enumr8

A javascript module for defining custom enum types and generating instances of that type.

##How to use

const createEnumType = require('enumr8');



//DAYS OF THE WEEK EXAMPLE/////////////////////////////////////////////////////

//define an enum type consisting of the days of the week
let Weekday = createEnumType(['Sunday',
                              'Monday',
                              'Tuesday',
                              'Wednesday',
                              'Thursday',
                              'Friday',
                              'Saturday']);

//retrieve first and last                               
console.log(Weekday.eFirst());
console.log(Weekday.eLast());

//retrieve the value of Friday
console.log(Weekday.Friday);

//get number of days in the week
console.log(Weeday.eLength)




let today = Weekday.eCreate('Tuesday');
console.log(today.getValue()); //Tuesday

today.increment();
console.log(today.getValue()); //Wednesday

today.add(3);
console.log(today.getValue()); //Saturday

today.add(2);
console.log("Today is now " + today.getValue());      //Monday

console.log("Yesterday was " + today.getPrevious());  //Sunday
console.log("Tomorrow is " + today.getNext());        //Tuesday

today.decrement();
console.log("Today is now " + today.getValue()); //Sunday

today.decrement();
console.log("Today is now " + today.getValue()); //Saturday

today.setByValue(Weekday.Thursday);
console.log("Today is now " + today.getValue()); //Thursday


//HEXADECIMAL EXAMPLE//////////////////////////////////////////////////////////

//define an enum type consisting of the symbols for hexadecimal
