Catching Node fs.existsSync errors

Does it make practical value to put fs.existsSync inside try...catch?

Is it possible that it will cause an error? How can this happen and which error would it be?

The reason I'm asking is because I'm trying avoid nested try...catch if possible.

fs.existsSync cannot throw an error.

Here is the implementation of fs.existsSync, in which try..catches its own errors and returns false when an error occurs.

Looking at the (current) implementation, it doesn't make sense to wrap it with try...catch:

fs.existsSync = function(path) {
  try {
    handleError((path = getPathFromURL(path)));
    nullCheck(path);
    binding.stat(pathModule._makeLong(path));
    return true;
  } catch (e) {
    return false;
  }
};
