The initLoadTasks function does something asynchronous, so you need to pass
it a callback function that will be invoked when it finishes.
If the only thing you want is a list of the files in a given directory, you
don't need to write initLoadTasks. You can just call fs.readdir.
However, supposing you want to do something more, here's how you could
write it in JavaScript.
var fs = require('fs');
function initLoadTasks(subDir, cb) {
fs.readDir(__dirname + '/' + subDir, function (err, files) {
if (err) {
return cb(err);
}
// do extra processing here
cb(null, files);
});
}
initLoadTasks('toRun', function (err, files) {
// do something with files here after checking err
});
