So. I use for this Javascript and Node.js . It's a simple program but because it's my first time working with modules and I have no idea what I am doing.
logger.js
let log= function(message){
console.log(format(message));
}
let format = function(message){
let dt = Date()
let msg = 'logger.js ('+dt.getFullYear+'-'+dt.getMinute+'): '+message;
return msg;
}
module.exports = log();
module.exports = format();
loggertest.js
let logger = require('./logger');
logger.log('Info: The new logger works perfectly!');
console.log(logger.format('Info: The new logger works perfectly!'));
The Error:
C:\programs\Node js Tasks\Logger>node loggertest
logger.js (undefined-undefined): undefined
C:\programs\Node js Tasks\Logger\loggertest.js:3
logger.log('Info: The new logger works perfectly!');
^
TypeError: logger.log is not a function

Would be nice if someone explains my Mistakes in detail to me. It's my first time with this all and I would like to know as much as possible, so I don't make the same mistakes again. Thanks for the help. ^^
let log = function (message) {
console.log(format(message));
}
let format = function (message) {
let dt = Date()
let msg = 'logger.js (' + dt.getFullYear + '-' + dt.getMinute + '): ' + message;
return msg;
}
module.exports = {
log,
format,
}
and then
const logger = require('./logger');
logger.log....
