Usage

Object initialization
const COLORS = class COLOR extends Enum {}.init({ 
    "RED": "red" ,
    "GREEN": "green" , 
    "BLUE": "blue"
});

console.log(COLORS[0] === COLORS.RED);   // "true"
console.log(COLORS[1] === COLORS.GREEN); // "true"
console.log(COLORS[2] === COLORS.BLUE);  // "true"

console.log(COLORS.GREEN.name);          // "GREEN"
console.log(COLORS.GREEN.text);          // "green"
console.assert(COLORS.GREEN.ordinal);    // "1"

console.assert(COLORS.GREEN + "");       // "green"
console.assert(COLORS.GREEN * 1);        // "1"



Array initialization
const COLORS = class COLOR extends Enum {}.init([ 
    "RED", 
    "GREEN",
    "BLUE"
]);

console.log(COLORS[2].name)               // "BLUE"
console.log(COLORS[2].text);              // ""
console.log(COLORS[2].ordinal);           // "2"

console.log(COLORS[2] === COLORS.BLUE);    // "true"

console.log(COLORS.BLUE + "");            // "BLUE"
console.log(COLORS.BLUE * 1);             // "2"



Ordinal value generator
class FLAGS extends Enum {};
FLAGS.init([ "FIRST", "SECOND", "THIRD", "FOURTH" ], 1, ord => ord<<1);

console.log(FLAGS.FOURTH | FLAGS.SECOND); // "10"
