What is the best possible way to write each element of an array to a new line of a file?

Question

For example this code writes the entire array to a single line:

var fs = require('fs');
fs.writeFileSync('myfile.txt', mydataarray, 'utf-8');

Where as this code needs a loop and multiple call to fs API.

for(var i = 0; i < mydataarray.length; i++){
  fs.appendFile('myfile.txt', mydataarray[i]+"\n", (err) => {
    if (err) throw err;
  });
}

Is there a way to do this at once like the first example?

How about

fs.writeFileSync('myfile.txt', mydataarray.join('\n'), 'utf-8');
