Hyphenation.
The hyphenated and camel-cased forms of the example word,
"background-color" and "backgroundColor" both wound up straddling the end of the line, and were set as
"background-
color"
and
"background-
Color"
The hyphen in the first instance is part of the spelling, and in the second instance an indication of hyphenation when breaking a single word; the unfortunate result is a confusing (if technically correct) presentation, which obfuscates the point it is intended to illustrate.
This is also inconsistent with the usage elsewhere in the book, in which camel-cased *keywords* are broken before an internal capitalized letter without adding a hyphen -- for example, earlier on the same page.
I have seen dictionaries which address the problem by having a special symbol (an oblique equals-sign) for end-of-line hyphenation, distinct from the hyphen glyph used as part of the normal spelling of a word.

In the Javascript object passed to animate(), the font-size property needs to be a string, ie
{"font-size": 10} instead of {font-size: 10}
Otherwise, the Javascript is not valid.
This is actually explained for "margin-left" on page 55, 1st paragraph.

3rd para. (The queue property...) |
"The queue property ... specifies whether the animation should be queued, or whether it should be deferred until..."
The intent of the conjunction "or" is unclear. Does is separate opposite choices (those for the values "true" and "false"), or alternative ways of describing the same choice ("true"), leaving the effect of of the alternative ("false") unstated. I understand it is used in latter sense. In any event the wording needs to be reworked.

The jQuery selector as printed in the book is:
p:nth-child(3n + 1):text(JavaScript):not(:has(a))
The :text selector in the book should be replaced with the :contains selector. That is, the line should read:
p:nth-child(3n + 1):contains(JavaScript):not(:has(a))
As printed in the book, the selector is syntactically incorrect (:text does not take a parameter) and semantically incorrect. :text looks for <input type='text'> elements when what we want is to find <p> elements that contain the word "JavaScript".
