Applications and Practical Use
Apart from having a basis in programming language theory, Racket was designed to be used as a general-purpose language in production systems. Thus, the Racket distribution features an extensive library that covers systems and network programming, web development, a uniform interface to the underlying operating system, a dynamic foreign function interface, several flavours of regular expressions, lexer/parser generators, logic programming, and a complete GUI framework, to name a few.
The design decision to make Racket a practical language has implications beyond the library, too. Those include Racket's ability to generate standalone executables under Windows, Mac OS X and Unix, a profiler and debugger included in the integrated development environment (IDE) and a unit testing framework.
Racket has been used for commercial projects and web applications. A notable example is the Hacker News website, which runs on Arc, which is developed in Racket. Naughty Dog has used it as a scripting language in several of their video games.

Famous quotes containing the words practical use and/or practical:
“Not many appreciate the ultimate power and potential usefulness of basic knowledge accumulated by obscure, unseen investigators who, in a lifetime of intensive study, may never see any practical use for their findings but who go on seeking answers to the unknown without thought of financial or practical gain.”
—Eugenie Clark (b. 1922)
“There are certain queer times and occasions in this strange mixed affair we call life when a man takes this whole universe for a vast practical joke, though the wit thereof he but dimly discerns, and more than suspects that the joke is at nobody’s expense but his own.”
—Herman Melville (1819–1891)
