Clojure 1.9 introduces notable features such as reader syntax for namespaced maps and improved predicate functions like atoms with swap/reset capabilities. It allows for easy installation and shell scripting without needing a .clj file extension, enhancing usability with tools like rlwrap for command history in REPL. Additionally, there are fixes for docstrings, making the language more user-friendly.

Cool Things in Clojure 1.9
- 1. What's new in Clojure 1.9 at least that I think are cool
- 2. Reader Syntax Namespaced Maps Only keywords or symbols are affected
- 3. Reader Syntax Namespaced Maps Even using the current namespace
- 6. Atoms: swap/reset Before 1.9 Save the value Modify it Or.. Don't do this at home You could have race conditions with something updating before you could copy it off Still ... a little ugly
- 7. swap-vals! Returns a vector with old val and new val reset-vals! Works the same way Destructuring
- 8. brew install clojure it gives you commands clj and clojure.
- 9. shell scripting anyone? Note: doesn't need .clj extension
- 10. Open a REPL Install rlwrap so you can press up for previous statement Also install rewrap by brew
- 11. deps.edn open a repl in the directory, dependancies are loaded
- 13. Thanks :)
