Why does it return NaN instead of text file content?

Question

Node.js

Hello, instead of the contents of the article.txt file, it gives NaN

var fs = require('fs');

var myReadShort = fs.createReadStream(__dirname + '/article.txt');

myReadShort.on('data', function(chunk) {
    console.log("Новые данные получены:\n", + chunk);
});

I checked that the file exists, the name is that, but in the end it still gives out:

Новые данные получены:
 NaN

Answer 1

You write a log to the console: string, COMMA, +chunk, it turns out that strings and a chunk with a unary plus are displayed, which leads it to a number, and as a result - NaN
