In your example, [1 2 3 4 5] allocates and initializes a vector with the 5
elements 1 2 3 4 5.
The first (def my-vec ...) also allocates a Var, and makes it 'point' at
the vector [1 2 3 4 5].
When you do (assoc my-vec 2 "hello"), it looks up the current value pointed
at by my-vec, which is the im
New to Clojure (find it fascinating so far, in large part due to watching
approximately a billion Rich Hickey vids on YouTube). I had a similar
question and figured I just resurrect this thread on it.
My naive thought was that when you (re)def a variable, you aren't actually
copying over the ol

I want to thank everyone for the helpful comments, and no worries
about the typing nickikt. I'll check out SICP. I've been playing
around in the repl, getting used to prefix notation, and I found out
the doc command. It makes learning this stuff much faster.
I guess I should have been more clear
Hello,
I have a some comments (on comments and more :))

There are diffrent kind ofs comments. If you just want to note
something you can do ; but mabey you want to have a example how to use
something in your Code then use (comment ).
With "defn" you creat a new f
I don't think that Structure and Interpretion of Computer Programs is
a good first-book if you want to start lisp-programming (Especially
Clojure). It's very detailed and gives much insights, but Clojure is
way more practical than this book. If you want to start programming
Clojure, I'd recommend "
If your are new to programming I recommend reading at least the first
three chapters of The Structure and Interpretation of Computer
Programs. It's available online.
