Why is END READ output, but the part before it is not output?

Question

Node.js

The console output is END READ, and the previous part is cut off. I must say right away that in previous programs this scheme worked as it should.
PS Yes, I may not see the obvious error. To some extent, I may not understand something. But I am writing a question in order to understand and understand.
Thanks in advance.

var fs=require ('fs');
var streamwrite=new fs.WriteStream(__dirname+"/read.txt",'utf-8');
var streamread=new fs.ReadStream(__dirname+"/read.txt",'utf-8');
streamread.on('data',function(chunk){
    console.log("Date accepted:\n"+chunk);
    streamwrite.write("Privet");
    console.log("Dannie zapisani");
  });
streamread.on('end',function(){
  console.log("THE END READ");
});
streamread.on('error',function(err){
  if(err=='ENOENT'){
    console.log("File not found");
  }
  else{
    console.error(err);
  }
});
