• Shares with Lisp the code-as-data philosophy and a powerful macro system.

• Favours immutable, persistent data structures (values don't change)
• Not a strictly pure language which makes it practical

Sum a list of numbers in Python:

>>> sum = 0
>>> for n in [1, 2, 3]:
...   sum = sum + n
... 
>>> sum
6

Sum a list of numbers in Clojure:

user=> (reduce + [1 2 3])
6

• Offers a software transactional memory system (think transactions in a database) and reactive Agent system that ensure clean, correct, multithreaded designs.

• Compiled at runtime allowing runtime access to all features
• Favours developing with a Read Eval Print Loop (REPL)

A basic set of examples can be found in src/intro/core.clj and ran in a REPL.

To run the examples:

• Clone this repository,
• Install Leiningen
• Change to the project directory and run lein repl to open a REPL that you can copy the examples into
