— Sorry i do not know this language

—

'use strict';

const { createInterface } = require('readline');
const { createReadStream, readFileSync } = require('fs');

const filepath = "...";

const asyncLines = [];

// async
createInterface({ input: createReadStream(filepath) }).on('line', line => {
  // this runs for every line
  asyncLines.push(line);
});

// sync
const syncLines = readFileSync(filepath, 'utf8')
  .split(/[\r\n]+/);

— Also, file:/// paths won't work

— Just use a regular path "/home/lvm/COC2/input.txt"

— Thakns, but i got still the same error

— 'FileReader' is not defined

— Did you save it?

— Sure

— I'm not using "FileReader" here

— So you must be running the wrong file

— How to print in the console the opened file line by line?

— Replace asyncLines.push with console.log
