path.join vs path.resolve with __dirname

Question

Is there a difference when using both path.join and path.resolve with __dirname for resolving absolute path in Node.js?

Answer 1

from doc for path.resolve:

The resulting path is normalized and trailing slashes are removed unless the path is resolved to the root directory.

But path.join keeps trailing slashes

So

__dirname = '/';
path.join(__dirname, 'foo/'); // '/foo/'
path.resolve(__dirname, 'foo/'); // '/foo'
