Errata

On the Amazon Kindle version of the book, using the third smallest font size, page 609 or otherwise under the section "Example: Hello World", subsection "Closure Templates", the compiled version of the soy template does not include the StringBuilder and the output is different, more specifically that the second parameter is "null|undefined" and the JS file requires 'soydata' instead of 'StringBuilder', so the example does not run. Here is my output I receive:

// This file was automatically generated from hello.soy.
// Please don't edit this file by hand.

goog.provide('example.templates');

goog.require('soy');
goog.require('soydata');


/**
* @param {Object.<string, *>=} opt_data
* @param {(null|undefined)=} opt_ignored
* @return {string}
* @notypecheck
*/
example.templates.welcome = function(opt_data, opt_ignored) {
return '<h1 id="greeting">' + soy.$$escapeHtml(opt_data.greeting) + '</h1>The year is ' + soy.$$escapeHtml(opt_data.year) + '.';
};


This is the second code example so it's a little disheartening. I hope the errata can address this.

In the code example on page 1081 of 14969 on the Amazon Kindle version, or alternatively in Chapter 2 under the section "Special @param Types", subsection "Variable number of parameters, the code example that starts: @param {function(string, string=)} has a typo. A line says this:

@param {function(string, ...[number]}:number}

when it should say

@param{function(string, ...[number]):number}
