Usage

import { Logger } from 'ts-tiny-logger';

// Create a logger instance
const logger1 = Logger.getInstance('app');

// Add log entries
logger1.log('init', 'Application started');
logger1.log('user', 'User logged in');

//   { dateTime: '2023-10-10:12-30-25-456', name: 'init', value: 'Application started' },

// ]

// Create another logger instance with a different name
const logger2 = Logger.getInstance('database');
logger2.log('connection', 'Database connected');

// The same instance is returned if the same name is used
