2nd paragraph

The following sentence: The following document is valid because the length of the lastName is ⇐ 20 should read: The following document is valid because the length of the lastName is <= 20 (less than or equal to 20 - looks like the word processing software has unhelpfully auto-miscorrected the <= into a left block arrow)

Final paragraph

The following sentence: The following document is valid because the length of the lastName exceeds 20 characters. should read: The following document is invalid because the length of the lastName exceeds 20 characters. (invalid - not valid) - looks like a copy/paste error from previous sentence with the <= typo reported previously.

http://schema.org/Person[http://schema.org/ Person has no closing square bracket. Probably can just remove [http://schema.org/Person and ensure that the original http://schema.org/Person is hyperlinked. Note also that schema.org now use https:// throughout, rather than http:// , although they provide an auto-redirect to the https:// equivalent.

The screenshot shows the command that should be entered - but this should also be shown in the text of the page, before the screenshot, for clarity and to make it available for copy/paste or screen readers (which generally cannot read text from bitmap graphics).

Second line from top of page

Appearing in Chapter 4, "If you'll recall from Chapter 6 (JSON Search), jq is an amazing command" - except that there is no previous mention of jq before page 115, so the reader cannot be expected to recall something that has not been previously introduced. Was chapter 6 (JSON Search) meant to appear earlier in the book?
