How to use

``javascript
import { createLogger } from '@hackforplay/log';

const logger = createLogger();

// Show all logs
logger.subscribe(console.info);

// Add a new line
const log = logger.log;
log('Hello World!');
`

Sharing loggers between independent libraries

As you use createLogger(), the shared reference will be injected in global. e.g. window in browsers or self in the Node.js.

`javascript
import { createLogger } from '@hackforplay/log';

const loggerA = createLogger();
const loggerB = createLogger();
console.log(loggerA === loggerB); // true

const loggerC = createLogger('You can use different reference with key string');
console.log(loggerA === loggerC); // false

// Yes, This is global injection :P
console.log(
loggerC === window['You can use different reference with key string']
); // true
`

If you hate this way, you can use constructor. This way DO NOT global injection.

`javascript
import { Logger } from '@hackforplay/log';

const logger = new Logger();

// Show all logs
logger.subscribe(console.info);

// Add a new line
const log = logger.log;
log('Hello World!');
