First of all “cheeseburgerpizzabagels” is not a word.
Second of all, you should check the terminal output because I did not see any “cheese” in the output so I could not solve the exercise.

Is assigning the ‘secret’ word to the variable secretWord ‘manually’ really the solution to this exercise?

Hi,

Can someone help me?

Why is the console.log('word: ’ + secretWord); executed first? The first output is “word: null”.
Why is the console.log(trimWord(data)); able to print the word, but the secretWord = trimWord(data); does not assign this value to the secretWord?

Any help would be highly appreciated. Thanks, F

yes, assigning the ‘secret’ word to the variable secretWord ‘manually’ is the solution to this exercise.

Here’s my code. It’s super gross, but runs the output again until it reaches a non txt file and then assigns the last word of the output to be the secret word, which passes.

I would like to see if anyone else has another recursive way which works better. I know mine only works because I know the file name and the secret word come last in the output string.

Like the others, it doesn’t pass without manually changing secretWord.

const fs = require('fs');

let secretWord = null;

let readDataCallback =(err, data) => {
  if (err) {console.log(`something went wrong: ${err}`)
  } else {
    const outputArray = data.split(" ")
    const nextFile = outputArray[outputArray.length-1];
    if (nextFile.split(".")[1] === 'txt') {
    fs.readFile(nextFile, 'utf-8', readDataCallback)
    } else {
      secretWord = nextFile;
      console.log(`secretWord = ${secretWord}`)
    };
  }
}

fs.readFile('./fileOne.txt', 'utf-8', readDataCallback);
