I agree that a more fitting line would have been, &quot;I show how to build a modern C++ high-performance, asynchronous echo server using Facebook&#x27;s Wangle (which comes out to be only 48 lines of code).<p>However the TITLE OF THE ARTICLE is &quot;Writing modern C++ servers using Wangle.&quot; Furthermore, the author states that he&#x27;s using that framework almost immediately after the statement you quoted, so I really see nothing to complain about. It would be more of an issue if the author led with a huge introductory paragraph or click-baity title that failed to mention the library she or he is using.<p>Knowing how many lines it took for the author to implement the server in the Wangle framework is very relevant to the reader.
