Errata in chapters 1 - 3
Here are some errata & apparent inconsistencies I've found while reading chapters 1 - 3.
p.28 html code sample has extra '>' character at end of line 3, giving invalid html syntax.
p.35 first para, line 2 'Youe' should be 'You'.
p.41 first para, line 4 ends with a '?' character - maybe should be ':'
p.41 'case sensitivity' section, first line, 'is a' should be 'is'.
p.51 first para, line 2, 'references' should probably be 'referenced'.
p.51 Figure 3-1, left hand side, 'null' and 'undefined' start with a lower case letter, but in many subsequent places (listed below) they start with an upper case letter. This is confusing if you're trying to understand how the language works at a basic level. Either they're 'null' and 'undefined' types, or they're 'Null' and 'Undefined' types, and the book should be consistent.
p.51 Figure 3-1, right hand side, 'Objects' should probably be 'Object' which is the type that the other reference types inherit from. There's no such type as 'Objects'. Alternatively, 'Object' should appear in the list.
p.54 table at bottom of page, left hand column: 'Null' and 'Undefined' - should they start with lower case letters (depending on the answer for Figure 3-1 on page 51 above) or not? Is this just the word processor automatically capitalising them as the first word in a 'sentence'?
p.56 two tables at bottom of page, left hand column, same query about 'Null' and 'Undefined' capitalisation consistency with Figure 3-1 on page 51.
p.57 table at top of page, left hand column, same query about 'Null' and 'Undefined' capitalisation as for p.56.
p.57 'composite to primitive conversion' section, first line, 'covert' should be 'convert'.
On the plus side, my early impressions about this book are good, and I like the conscientious style in which it's written. Looking forward to reading the rest of it.
