Adding backslash to string

Question

var myString = '\\folder\folder1\folder2\folder3\anotherFolder\filname.pdf';

The goal is to get

myString = '\\\\folder\\folder1\\folder2\\folder3\\anotherFolder';

My first idea was to split on each backslash, do a loop to create the new string. I got this result for the split

myString.split('\\'); ["", "folderolder1older2older3anotherFolderilname.pdf"]

The first string has a single backslash in it - at the beginning. `\f` is just an escaped character `f`. — VLAZ, Sep 27 '22 at 13:40
There is only on backslash in the string literal. `\f` is a single character. `'\f'.length === 1` and `'\f'.charCodeAt(0)` it returns 12, the Form Feed character: https://unicode-table.com/en/000C/ — adiga, Sep 27 '22 at 13:41

var myString = 
String.raw`\\folder\folder1\folder2\folder3\anotherFolder\filname.pdf`;
var mySplit = myString.split('\\');
var result;

for (var i =0; i<(mySplit.length-1);i++){
    result = result +'\\'+mySplit[i];

}

result = result.replace('undefined','\\');

Result is

"\\\\folder\folder1\folder2\folder3\anotherFolder"
