How to create a directory if it doesn’t exist using Node.js

Is the following the right way to create a directory if it doesn’t exist?

It should have full permission for the script and readable by others.

var dir = __dirname + '/upload';
if (!path.existsSync(dir)) {
    fs.mkdirSync(dir, 0744);
}

For individual dirs:

var fs = require('fs');
var dir="./tmp";

if (!fs.existsSync(dir)){
    fs.mkdirSync(dir);
}

Or, for nested dirs:

var fs = require('fs');
var dir="./tmp/but/then/nested";

if (!fs.existsSync(dir)){
    fs.mkdirSync(dir, { recursive: true });
}
