Check nodejs path exists

I only want to know whether a path exists. Here's my code:

var path = require('path'); // exists path

try:

var path = require('path');
if (path.existsSync("/the/path")) { // or fs.existsSync
    // ...
}

or

fs.exists('/the/path', function (exists) {
    util.debug(exists ? "it's there" : "no exists");
});
