17. – Robert C. Martin, Clean Code: A Handbook of Agile Software Craftsmanship “It is not the language that makes programs appear simple. It is the programmer that make the language appear simple.”
18. WHY SHOULD WE LEARN? — Have more opportunities — Make right decisions — Just for fun — Grow up as engineers
20. HISTORY OF LANGUAGES . 1822 Charles Babbage’s difference engine (mechanical computation of polynomial functions) . 1942 ENIAC (electrical signals) . 1945 John Von Neumann (shared-program technique & conditional control transfer) . 1957 FORTRAN (FORmula TRANslating system. Procedural programming. IF, DO, GOTO, basic types, alternative to assembly language)
21. HISTORY OF LANGUAGES . 1958 LISP (LISt Processing. The first dynamically typed functional programming language. Designed for AI, tree data structures, automatic storage management) . 1959 COBOL (Common Business-Oriented Language. numbers, strings, arrays, records) . 1964 BASIC (Beginner’s All-purpose Symbolic Instruction Code. GC) . 1968 Pascal (teaching purpose, structured programming, improved the “pointer” data type CASE)
22. HISTORY OF LANGUAGES . 1972 C (Dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output) . 1980 Smalltalk (OOP. MVC, reflection) . 1983 C++ (C With Classes. Virtual functions and templates) . 1983 Objective-C (Message-passing functionality based on Smalltalk language) . 1986 Erlang (concurrent programming)
23. HISTORY OF LANGUAGES . 1987 Perl (Practical Extraction and Reporting Language, report processing, improved version of sed and awk tools) . 1990 Haskell (purely functional programming) . 1993 Ruby (Designed for productive and enjoyable programming) . 1995 Java (Cross-platform functionality) . 1995 JavaScript (prototyping model)
24. HISTORY OF LANGUAGES . 2001 C# . 2003 Scala . Clojure 2007 . 2009 Go . Rust 2010 . 2012 Elixir

27. CLOJURE
28. CLOJURE
29. CLOJURE 1. “Cambridge Polish” syntax (S-expressions) 2. “Data as code” strategy 4. Lazy Evaluation 5. STM (software transactional memory) 3. Macro system and protocols KEY FEATURES
30. CLOJURE “S-EXPRESSIONS” SYNTAX OR(x, y) vs x OR y
31. CLOJURE “DATA AS CODE” STRATEGY Homoiconicity* Language text has the same structure as its abstract syntax tree (AST) * https://en.wikipedia.org/wiki/Homoiconicity Clojure code is just nested lists of symbols that can be evaluated
32. CLOJURE MACRO SYSTEM & PROTOCOLS
33. CLOJURE LAZY EVALUATION
34. CLOJURE STM
35. CLOJURE TOOLS ClojureScript https://github.com/razum2um/awesome-clojure Datomic Leiningen Ring … Core.async Luminus
36. CLOJURE REAL EXAMPLES https://clojure.org/community/companies
37. CLOJURE CONS PROS + the ecosystem (JVM) + concurrency + data is code - prefix notation - readability - learning curve

48. GO TOOLS Bigcache https://github.com/avelino/awesome-go CockroachDB Godoc Testing … Gin
49. GO REAL EXAMPLES https://github.com/golang/go/wiki/GoUsers Need some more?
50. GO CONS PROS + learning curve, simplicity + GC + no VM - no REPL - no generics - size of binaries + infrastructure + concurrency - pointers

53. ELIXIR CLEAR CODE IS BETTER THAN CONCISE CODE
54. ELIXIR 1. Pipeline operator, pattern matching, destructuring 2. Metaprogramming & macroses 4. Actors & Agents 5. Erlang/OTP 3. Polymorphism via protocols KEY FEATURES
55. ELIXIR |>, PATTERN MATCHING, DESTRUCTURING
56. ELIXIR METAPROGRAMMING & MACROSES AST -> MACROS -> AST https://qed.elixir.pm/

61. ELIXIR REAL EXAMPLES https://github.com/doomspork/elixir-companies
62. ELIXIR CONS PROS + the ecosystem (Erlang, Phoenix, Ecto) + concurrency + syntax, readability - small amount of libraries - deployment process + learning curve
