F#

I'm used to imperative/OO programming (know C, C++, Python, PHP, etc.). I wanted to get into functional programming but there are some things unclear to me.

Take for example the languages F# and Haskell:

How do you implement loops? By recursion? Eew.
What about conditions?
How can you get by without variables?

I mean.. What do we have RAM for.. storing variables, right?

When would you NOT want to use functional programming? What is it not so good at? I am more looking for disadvantages of the paradigm as a whole, not things like "not widely used", or "no good debugger available". Those answers may be correct as of now, but they deal with FP being a new concept (an… >>> More
Should functional programming be taught before imperative programming?

It seems to me that functional programming is a great thing. It eliminates state and makes it much easier to automatically make code run in parallel. Many programmers who were first taught imperative programming styles find it very difficult to learn functional programming, because it is so different… >>> More

Learning Haskell: How to remove an item from a List in Haskell

Trying to learn Haskell. I am trying to write a simple function to remove a number from a list without using built-in function (delete...I think). For the sake of simplicity, let's assume that the input parameter is an Integer and the list is an Integer list. Here is the code I have, Please tell me… >>> More
