This file contains errors that are likely to prevent the code examples from working as described in ths book. See this file for small mistakes that I intend to correct in the next edition.
Chapter 1
On page 22, the type package installed by Listing 1-31 should specify a version, like this:
npm install --save-dev @types/[email protected]
(Thanks to J Fern for reporting this problem)
Chapter 10
The example in Listing 10-22 doesn't produce the expected results because, as the chapter notes, there is no intersection between the number and string types. Please ignore the results from this listing.
(Thanks to Bersez Nathan - aka GazousGit - for reporting this issue)
Chapter 13
The command in Listing 15-13 may produce the following error:
[webpack-cli] TypeError: options.forEach is not a function
To resolve this issue update the webpack-cli package using the following command:
npm update webpack-cli
