MySQL Question

NodeJS + mysql - automatically closing pool connections?

I wish to use connection pooling using NodeJS with MySQL database. According to docs, there are two ways to do that: either I explicitly get connection from the pool, use it and release it:

var pool = require('mysql').createPool(opts);

pool.getConnection(function(err, conn) {
conn.query('select 1+1', function(err, res) {

Or I can use it like this:

var mysql = require('mysql');
var pool = mysql.createPool({opts});

pool.query('select 1+1', function(err, rows, fields) {
if (err) throw err;

console.log('The solution is: ', rows[0].solution);

If I use the second options, does that mean, that connections are automatically pulled from the pool, used and released? And if so, is there reason to use the first approach?
