Lecture 14 Introduction to Racket Dan Grossman Fall 2011 Racket Next 2 weeks will use the Racket language not ML and the DrRacket programming environment not emacs Installation basic usage instructions on course website. Lecture 11. Closures-. ish. Java & . C. Dan Grossman. Fall 2011. Higher-order programming. Higher-order programming, e.g., with . map. and . filter. , is great. Language support for closures makes it very pleasant. Lecture 12. Modules. Dan Grossman. Fall 2011. Modules. For larger programs, one “top-level” sequence of bindings is poor. Especially because a binding can use . all. earlier (non-shadowed) bindings. Lecture 18. Static vs. Dynamic Typing. Dan Grossman. Fall 2011. Static vs. dynamic typing. A big, juicy, essential, topic about how to think about PLs. Conversation usually overrun with half-informed opinions . Lecture 9. Function-Closure Idioms. Dan Grossman. Fall 2011. More idioms. We know the rule for lexical scope and function closures. Now what is it good for. A partial but wide-ranging list:. Pass functions with private data to iterators: Done. Lecture 25. Subtyping for OOP;. Comparing/Combining Generics and Subtyping . Dan Grossman. Winter 2013. Now…. Use what we learned about subtyping for records and functions to understand subtyping for class-based OOP. CS 170b. Benjamin Gaska, much help from William Mitchell. What is a programming language. A simple definition:. A system for describing computation.. It is generally agreed that in order for a language to be . Lecture 14. Thunks. , Laziness, Streams, . Memoization. Dan Grossman. Spring . 2017. Delayed evaluation. For each language construct, the semantics specifies when . subexpressions. get evaluated. In ML, Racket, Java, C:. Lecture 17.

Functional programming. ” can mean a few different things:. Avoiding mutation in most/all cases (done and ongoing). Lecture . 6. Nested Patterns. Exceptions. Tail Recursion. Dan Grossman. Spring . 2013. Nested patterns. We can nest patterns as deep as we want. Just like we can nest expressions as deep as we want. Often avoids hard-to-read, wordy nested case expressions. Lecture . 22.
