JavaScript slice() working differently locally than online using Github site

Question

I'm parsing text file using Javascript. On the lines I have slice() function, my code appear to behave differently on local host and online

for example

if(connection == 'local') {
     value = d.substring(split2, split3).substr(1).slice(0, -1);
}
else if(connection == 'online') {
     value = d.substring(split2, split3).substr(1);
}

However this piece of code solve it but I cannot understand the behavior, it seems like when I use my code online that are extra hidden characters on the text file or something

`\r\n` vs `\n` probably... Look [here](https://stackoverflow.com/a/39532890/2159528) — Louys Patrice Bessette, Jun 06 '21 at 22:56
You're going to need to provide a lot more context. How is `connection` determined? What exactly are the sources of `d`? How are you running your code both locally and online? The issue is not in the code you've currently got in the question. — Tibrogargan, Jun 06 '21 at 22:56

you can do

value = d.substring(split2, split3).substr(1).trim();

trim() should remove any spaces and Escape Sequences.

some Escape sequences are hidden when you tries to debug your app, for example if you have `"\rfoo"` it will be shown as `"foo"` but actually it's not. – Tariq Mamdouh Jun 07 '21 at 00:27
yes I think its about \r but whats the difference between localhost and online server? – zEn feeLo Jun 07 '21 at 00:38
