inb4 muh JVM muh no TCO muh muh trampoline

Worthless shit like any lithp.

I can't believe clojure not having TCO. That seems very unlikely.

it does have it

Only in a limited and half-assed way.

But the JVM is fast

It's a lisp for JVM platforms. If you think that would be useful, learn it. Otherwise, don't.

So you have no opinion on it?

But the JVM is a goodbye to having any free memory.
Also, Clojure is not fast.

It is a very nice language, as long as you do not expect it to be something that it is not.

It is not a very nice language, unless you expect it to be something which it is.

No I don't, because he talks like a dumbass cunt that cannot express thoughts coherently.

Clojure is a functional programming language based on s-expressions that works tightly with the JVM for integration with Java code.

With that in mind, the advantages and disadvantages are self-explanatory:

Advantages:
Ability to extend Java code with Clojure
Ability to extend Clojure code with Java
Functional programming paradigm

Disadvantages:
JVM start up time
JVM memory usage
JVM doesn't support TCO

You can't use FP paradigm without proper TCO.

A language cannot be functional without purity. A language cannot be good without a syntax. A language cannot be efficient if it runs only on JVM.
The only good thing in Clojure is its concurrency and parallelism primitives.

Full TCO in the latter case is not possible on the JVM at present whilst preserving Java calling conventions (i.e without interpreting or inserting a trampoline etc).
So Clojure doesn't have proper TCO. OK, it's not a real functional language then.

JVM start up time

If you do not specifically want the JVM integration, I would not recommend Scala as a language for concurrency and parallelism.

I think TCO is misunderstood. It is not about iteration as there are other ways to implement it which are as functional albeit less cute, such as Clojure's recur special form. TCO really is about the freedom of jumping around functions without fear of stack overflows and it has applications from mutual recursion to finite-state machines including so-called “threaded” bytecode interpreters.
