lisp syntax is as clean and logical (other than maybe only having prefix operators and Lots of Insidiously Silly Parentheses) as you can get because there's very little of it.

lisp is also awesome because lisp macros are awesome

JavaScript is pretty amazing cause you can use one language for both client side and server side. No more learning a dozen languages to make your web app. One is all you need.

you can do this with clojure and actually use a lisp for real programs, it's pretty cool i highly recommend it

also gently caress json, s-expressions 4ever

i could, but when every time you read something/someone saying that java is miserable it becomes more and more of a turnoff to ever learn. i have a basic grasp of objective-c (though i need to work on learning actual design for ios at some point), but i was going to spend some time actually learning c itself because there's a lot of c stuff that you don't really need to touch in objective-C/ios dev.

to weed out the undesirables we always ask:

for a given string, output a list of unique characters and their number of occurrences

like 90% of applicants can't figure it out

i had one place ask me during an interview to determine if a string is a rotation of another, so i go and write a hacky longest common substring algo and get 'er done as they say

apparently it's one of those trick ones where you just concat the string and to a strstr. shame on me for not reading the "tricks of the trade: ace the programming interview!!!!" book

_.each(string.split(""), function(char) { counts[char] = counts[char]+1 || 1 }); is a cool one-liner but it's not like there's anything with just using a for loop

one liners are masturbation

code:
_.chain("abcaddaaaa".split(""))
 .groupBy(_.identity)
 .each(function (v,k) {

a map is implemented using trees (typically binary)

a dictionary is implemented using hash tables

both a map and a dictionary are associative containers.

there is no such thing as an "associative array".

i'm sure you are aware that java has treemap and hashmap for those distinctions

clojure's the most "modern" lisp and doesn't have alot of the cruft and implementation issues that CL and Scheme have. It's also got a lot of nice features like data structures as functions and super cool lambda syntax adn lots of nice functional programming stuff, and a heavy focus on concurrency which i've never cared about but you might. It does have a lot of dumb problems though, e.g:
  • (= false (contains? [3 3 3] 3))
  • terrible stack traces (although they used to be worse!)
  • p much everything to do with strings
  • have to call out to java libraries even for simple stuff like Math/sqrt
  • terrible docs
  • i still don't know nor care what the difference between refs, vars, atoms, and agents is
anyway on the whole i'd say go for it, but just be prepared to want to pull your hair out until you get into the swing of it.

contains? is kind of weird but it does help you not do a O(n) search of the vector. this is a stupid name for that call, i def agree
stack traces are what they are: awful and very java specific. Things got better with 1.3/1.4 but you still should know some java to be able to really understand wtf is going on. also download the source from github, it has helped me a lot, error messages sometimes don't make a lot of sense when a you call a macro incorrectly, and it blurts out a bunch of bullshit about Var cannot be cast to ISeq or w/e
strings aren't so bad... What issues did you have? all clojure strings are java.lang.String so they're easy to work with imo
the java math stuff isn't too bad, and you can always remap Math/sqrt to (defn sqrt Math/sqrt) or use a library
re: docs, i use clojuredocs.org and it's much better than clojure.org's poo poo
vars are just bindings, you can make them thread local if you need, refs are STM backed vars, agents are a FIFO queue, thread pooled, STM system, and atoms are like synchronous agents, i think. i've never used atoms.

clojure rules because it has a really strong focus on high quality, robust and fast data structures, and it has just a tad of syntax for using them literally (eg. [] vector {} map #{} set '() list), and the ISeq interface makes dealing with them really nice. working with any kind of complex data structure is much easier in clojure than any other language i've ever worked with

clojure has kind of a cool ecosystem too, check out incanter or core.logic for example

there's my carepost for the day
