The author seems to have no idea the actual meaning of the word "refactor". Most every code change is described as a "refactor" even when the change alters external behavior, even when the change fails to improve internal attributes or functionality.
Some React features being shown are not actually available in the 16.7 alpha version being shown, for example React.useState. Apparently this functionality is not present in 16.7, but does exist in the yet to be released 16.8 version. A work-around exists if you Google a bit.
Some React features being taught are deprecated, for example: React.SFC.
The author appears to have a working knowledge of React but isn't really keeping up on recent React changes. I'm just finishing the book in January 2019 after it was published in November 2018 and it appears to already have much out of date information.
There is no shortage of typos and grammatical errors, a total quality control failure.
