JavaScript's split() method automatically adds the \r character at the end of the string

Question

I'm trying to create an array with the fetched data and create a new collection with it, but the resulting string has \r at the end:

export const WordSetFn = async () =>{
    let wordSet;
    await fetch(wordsSet).then((resp) =>
        resp.text()
    ).then((resp) =>{
        const wordSetArray = resp.split("\n")
        wordSet = new Set(wordSetArray)
    })
    return {wordSet};
} // word set would look like this: {"above\r",...}

And the txt file I'm getting the data from is a bunch of words, each word is on the next line, like this:

aback
abase
abate
abbey
abbot
Abhor
Abide
abled
Abode
abort
...

Now why is \r added after every word? What does \r mean?

Answer 1

\r is a carriage return character, \n is a line feed character, \r\n is a carriage return character plus a line feed character.
