Are these two patterns to write to a stream equivalent (e.g backpressure handling) ?

backpressure code patterns

//Pattern 1

var stream1 = fs.createWriteStream('some/path1');

function write1() {
  var more = stream1.write('something1');
  if (more) 
    write1();
  else 
    stream1.once('drain', write1);
}

write1();

//Pattern 2

var stream2 = fs.createWriteStream('some/path2');

function write2() {
  stream2.write('something2', write2);
}

write2();
