Here is a JavaScript class example.

'use strict';   class MyClass {     static get CHARACTER_TO_NUMBER() {         return {             'a': 1,             'b': 2,             'c': 3,         };     }       options = {};       publicVariable = 'some public value';     #privateVariable = 'some private value';       constructor(options) {         console.info('MyClass.constructor');         console.log('MyClass.constructor.options:', options);         this.options = options;         this.displayOptions();           console.log('this.privateVariable:', this.#privateVariable);     }       getCharacterFromNumber(number) {         console.info('MyClass.getCharacterFromNumber');         console.log('MyClass.getCharacterFromNumber.number:', number);         var character = MyClass.CHARACTER_TO_NUMBER[number];         console.log('MyClass.getCharacterFromNumber.character:', character);         return character;     }       displayOptions() {         console.info('MyClass.displayOptions');         console.log('this.options:', this.options);     } }   var mc = new MyClass({     'debug': true,     'some_option': 'some_value', });   var result = mc.getCharacterFromNumber('b'); console.log('mc.result:', result); console.log('mc.publicVariable:', mc.publicVariable);

Output:

MyClass.constructor MyClass.constructor.options: { debug: true, some_option: 'some_value' } MyClass.displayOptions this.options: { debug: true, some_option: 'some_value' } this.privateVariable: some private value MyClass.getCharacterFromNumber MyClass.getCharacterFromNumber.number: b MyClass.getCharacterFromNumber.character: 2 mc.result: 2 mc.publicVariable: some public value
