Q.js - Using deferred

How do I get the value of the text from the example below?

Answer 1

You can get the value via the .then() method of a Promise:

function read() {
    // your snippet here...
}

read().then(function (text) {
    console.log(text);
});

Also, error handlers can be passed either as a 2nd argument to .then() or with the .fail() method:

read().fail(function (err) {
    console.log(err);
});
