Editing "Hello, World!" program (section)

==Time to Hello World==

"Time to hello world" (TTHW) is the time it takes to author a "Hello, World!" program in a given programming language. This is one measure of a programming language's ease of use. Since the program is meant as an introduction for people unfamiliar with the language, a more complex "Hello, World!" program may indicate that the programming language is less approachable.<ref name="ODwyer">{{cite book |last1=O'Dwyer |first1=Arthur |title=Mastering the C++17 STL: Make full use of the standard library components in C++17 |date=September 2017 |publisher=[[Packt Publishing Ltd]] |isbn=978-1-78728-823-2 |page=251 |url=https://books.google.com/books?id=zJlGDwAAQBAJ&q=%22TTHW%22&pg=PA251 |access-date=4 December 2019 |language=en}}</ref> For instance, the first publicly known "Hello, World!" program in [[Malbolge]] (which actually output "HEllO WORld") took two years to be announced, and it was produced not by a human but by a code generator written in [[Common Lisp]] {{see above|{{slink||Variations}}, above}}.

The concept has been extended beyond programming languages to [[Application programming interface|APIs]], as a measure of how simple it is for a new developer to get a basic example working; a shorter time indicates an easier API for developers to adopt.<ref>{{cite web |last1=Wiegers |first1=Harold |title=The importance of "Time to First Hello, World!" an efficient API program |date=28 June 2018 |url=https://apifriends.com/api-management/api-program-time-first-hello-world/ |access-date=19 February 2020 |archive-date=19 February 2020 |archive-url=https://web.archive.org/web/20200219061813/https://apifriends.com/api-management/api-program-time-first-hello-world/ |url-status=live}}</ref><ref>{{cite book |last1=Jin |first1=Brenda |last2=Sahni |first2=Saurabh |last3=Shevat |first3=Amir |title=Designing Web APIs: Building APIs That Developers Love |url=https://books.google.com/books?id=Dg1rDwAAQBAJ&q=%22time%20to%20hello%20world%22&pg=PT150 |date=29 August 2018 |publisher=O'Reilly Media |isbn=9781492026877 |access-date=19 February 2020}}</ref>
