так логичнее ...

Еще логичнее классом все это оформить.

class Logger {
    arr = [];
	
	add (type, message) {
        this.arr.push({type, message, dateTime: new Date()});
	}
    warn(message) {this.add ('warn', message)}
 
    error(message) {this.add ('error', message)}
 
    log(message) {this.add ('log', message)}
 
    getRecords(stype) {
        return this.arr.filter(({type}) => stype == type);
    }
};
 
// examples
const logger1 = new Logger();
logger1.log('User logged in');
logger1.warn('User is tring to ented restricted page');
logger1.log('User logged out');
logger1.error('Unexpected error on the site');

console.log(logger1.getRecords('log')); // ===> [{ message: 'User logged out', type: 'log', dateTime: Date }, { message: 'User logged in', type: 'log', dateTime: Date }]
