and I would like to remove the first and last slash

Answer 1

Just in case that someone needs a premature optimization here...

var path = '///foo/is/not/equal/to/bar///'
var count = path.length - 1
var index = 0

while (path.charCodeAt(index) === 47 && ++index);
while (path.charCodeAt(count) === 47 && --count);

path = path.slice(index, count + 1)
