MY FIRST ASYNC I/O! (Exercise 4 of 13)

project.js

var fs = require('fs'); 

var content = fs.readFile(process.argv[2],function(err,data){ 
    if(err){
        console.log('error');
    }
    var lines=data.toString().split('\n');
    console.log(lines.length-1);
});

@Dipanshu27 the code seems to be wrong in this part :

var strFile = bufFile.toString();

The callback (err,data) second parameter data acts as the buffer.

The modified code is :

if(err){
console.log('error');
}
var strFile = data.toString();
var cnt = strFile.split('\n');
console.log(cnt.length - 1);
}); 

Cheers ! 👍

const fs = require("fs");
const file = process.argv[2];

fs.readFile(file, "utf8", function (err, contents) {
  if (err) {
    return console.error(err);
  }
  const lines = contents.split("\n").length - 1;
  console.log(lines);
});
