<p>These are the known mistakes in the <strong>third edition</strong>

of the book. For errata in the first edition,

see <a href="https://eloquentjavascript.net/1st_edition/errata.html">this

page</a>. For the second edition,

see <a href="https://eloquentjavascript.net/2nd_edition/errata.html">this

page</a>. To report a problem that is not listed

here, <a href="mailto:marijnh@gmail.com">send me an email</a>.</p>

<p>Issues whose page number is followed by an ordinal number are only

present up to the print denoted by that number. I.e. those followed by

“1st” were fixed in the second print.</p>

<h2>Chapter 2</h2>

<p><strong>Page 34</strong> (1st) <em>Updating Bindings Succintly</em>: Where it

says <code>counter-</code> it should be <code>counter--</code>.</p>

<h2>Chapter 6</h2>

<p><strong>Page 111</strong> (2nd) <em>Inheritance</em>: In the second

paragraph below the example code, instead of “<code>content</code>

method”, the text should say “<code>element</code> function”.

<h2>Chapter 8</h2>

<p><strong>Page 134</strong> (2nd) <em>Error Propagation</em>: In the third

paragraph of the section, a function <code>promptInteger</code> is

referred to. The function is actually

called <code>promptNumber</code>, and the word “whole” should be

dropped from the sentence (it accepts non-whole numbers, too).</p>

<h2>Chapter 10</h2>

<p><strong>Page 168</strong> (1st) <em>Modules as Building Blocks</em>: In “each

needs it own private scope“, it should say “<em>its</em> own private

scope“.</p>

<h2>Chapter 14</h2>

<p><strong>Page 234</strong> (2nd) <em>Creating Nodes</em>: In the

code, “edition” is misspelled as “editon”.</p>

<h2>Chapter 16</h2>

<p><strong>Page 285</strong> (2nd) <em>Pausing the Game</em>: The text

refers to the <code>arrow</code> binding, where it should

say <code>arrowKeys</code>.</p>

<h2>Chapter 20</h2>

<p><strong>Page 369</strong> (1st) <em>Directory

Creation</em>: <code>MKCOL</code> stands for “make collection”, not “make

column” as the book claims.</p>
