Node.js Array to text with newline

I wanted to convert an array to a textfile with a newline separating each entry.

I found out about an npm package called array-to-txt-file.
Here is the webpage:
array-to-txt-file

This package claims that will concatenate every element of the array with a newline, so that every element of the array appears on its own line on the text file.

So i gave it a try and while it works great it doesn't concatenate the elements with a newline. Where one element ends, another one begins.

So i took a look at the source code of the package and this is the code that creates this effect.

try {
array.forEach(v => {
if(_.isPlainObject(v)) {
ws.write(`${JSON.stringify(v)}n`)
return
}
ws.write(`${v}n`)
})


Especially the ws.write(${v}n) part.

ws.write(

)

I then imported my output text file into a hex editor. In the hex editor there was dot between each element. Now, this dot was different to a regular dot.

While a regular dot has the hex value of 2E, the dot that appears between the elements has 0A.
Please also note that i am using Windows 7, and when viewed with notepad, nothing appears between the elements - where one ends, another one begins straight up.

2E

0A

So is there a way to modify that line in the code i posted above, so it really creates a newline in that part?

n

Is there some reason a simple join doesn't work for you?

join

let arr = ["a", "b", "c", "d", "e", "f"];

console.log(arr); // [ 'a', 'b', 'c', 'd', 'e', 'f' ]

console.log(arr.join('n'));
// a
// b
// c
// d
// e
// f

let text = arr.join('n');

fs.writeFileSync('modified.txt', text, "utf8");


If you need to you can replace n with rn in the join as @Saif suggests, but I don't seem to need to, perhaps vscode is doing this automatically for me though. I'm on a Windows machine.

n

rn

r

n

On Linux, n represents new line.

n

Two characters combined rn represent a new line on Windows.

rn

Try replacing n with rn in both the write statements inside index.js file of the module.

n

rn

write

index.js

Those dots represent non-printable characters. While the regular dot . FULL STOP (U+002E) is represented by 2E.

2E
