Answer 1

Best is to use regex to replace all occurrences:

C:\\backup\\".replace(/\/\//g, "/")

this returns: C:\backup\

OR

use split()

"C:\\backup\\".split();

both produces your desired result

C:\backup\

console.log("using \"C:\\backup\\\".replace(/\/\//g, \"/\")")
console.log("C:\\backup\\".replace(/\/\//g, "/"));

console.log("Using \"C:\\backup\\\".split()");
console.log("C:\\backup\\".split());

Answer 2

This should do it: "C:\\backup\\".replace(/\\\\/g, '\\')

In the regular expression, a single \ must be escaped to \\, and in the replacement \ also.
