Example 2-11. Execution order of callbacks used by promises

var promise = new Promise(function (resolve, reject) {
	console.log('Inside the resolver function');    // 1
	resolve();
});

promise.then(function () {
	console.log('Inside the onFulfilled handler');  // 3
});

console.log('This is the last line of the script'); // 2

// Console output:
// Inside the resolver function
// This is the last line of the script
// Inside the onFulfilled handler
