1. Presented by Julian Togashi & Ryan Lewis CPSC 476, CSUF

2.  We will briefly cover two areas: 1. Define Clojure as a language ◦ (imperative languages v. functional languages) 2. Perform a SWOT Analysis ◦ Strengths, Weaknesses, Opportunities and Threats

3.  Functional Programming Language ◦ (a flavor of LISP)  State separated from Objects ◦ (persistent data structures)  Robustly supports concurrency ◦ (functions natively execute in transactions)  Built upon prevalent platform ◦ (runs on JVM)

6.  Targets JVM, CLR (Common Language Runtime, and Javascript  Compiles directly to JVM bytecode  Dynamic language - Polymorphism  Dialect of LISP  Immutable persistent data structures  Strong multithreaded design  Heterogeneous collections, return types  Identities (values emphasis)  Ideal for transactions  Uses REPL (Read, Execute, Print, Loop)  Can be embedded in a Java program  Can be used as a scripting language  Infix notation does not require precedence rules  Less configuration required than Java Apps  Lazy Sequences  Easily model infinite sequences  Java Interoperability

7.  Exciting ecosystem  Easily supports concurrent operations  General purpose programming  Native GAE support  AI development like NPCs and Expert Systems  Web applications  Mathematical systems  Responsive testing – updates easily deployed

8.  Not currently interoperable with.Net  Syntactically different that traditional C++/Java programs  Slow Start Up from JVM (in particular command line)  No-tail recursion optimization

9.  Introduced in 2007 so relatively new  Infant community support  No classes / Functional Syntax  No object orientated support  IDE support is still relatively immature  Not currently common in client projects
