locustjs-enum

This library provides utilities to define C# enum like objects

example:

const Color = Enum.define({ red: 0, green: 1, blue: 2}, 'Color');

console.log(Color.name);    // Color
console.log(Color.green);   // 1
console.log(Color['green']);  // 1
console.log(Color[1]);    // green

console.log(Color.isValid(1));  // true
console.log(Color.isValid(4));  // false
console.log(Color.isValid('green'));  // true
console.log(Color.isValid('Green'));  // false

console.log(Color.equals(Color.red, 0));  // true
console.log(Color.equals(Color.red, '0'));  // true
console.log(Color.equals(Color.red, 'red'));  // true

console.log(Color.getString(Color.red));  // 'red'
console.log(Color.getString('red'));    // 'red'
console.log(Color.getString('0'));    // 'red'
console.log(Color.getString('Yellow')); // undefined
console.log(Color.getString(5));      // undefined
console.log(Color.getString('Yellow', 'green'));  // 'green'
console.log(Color.getString(5, 'green')); // 'green'
console.log(Color.getString(5, 'Yellow'));  // 'red'

console.log(Color.getNumber(Color.red));  // 0
console.log(Color.getNumber('red'));  // 0
console.log(Color.getNumber(0));    // 0
console.log(Color.getNumber('0'));  // 0
console.log(Color.getNumber(5));  // undefined
console.log(Color.getNumber(5, 'green')); // 1
console.log(Color.getNumber(5, 'Yellow'));  // 0

console.log(Color.getNames());  // ['red', 'green', 'blue']
console.log(Color.getValues()); // [0, 1, 2]
console.log(Color.toArray()); // [{ name: 'red', value: 0 }, { name: 'green', value: 1 }, { name: 'blue', value: 2 }]

console.log('Testing enum value equality ...');

// 1. using Enum.equals
console.log(Enum.equals(Color, 1, 'green'));   // true
console.log(Enum.equals(Color, '1', Color.green)); // true
console.log(Enum.equals(Color, 1, 'Green'));   // false
console.log(Enum.equals(Color, 'green', Color.red)); // false

// 2. using equals() in enum type
console.log(Color.equals(1, 'green'));   // true
console.log(Color.equals('1', Color.green)); // true
console.log(Color.equals(1, 'Green'));   // false
console.log(Color.equals('green', Color.red)); // false
