I don't quite understand this sentence: Maybe for professionals and hard-core...

>>Maybe for professionals and hard-core hobbyists, you are correct. But for "casual" programmer, it' overkill and not so friendly.<<

The second sentence is grammatically too weird for me. What's the exact meaning of it? Something like... it's overkilling and not so friendly... maybe?

This " it' " is confusing me. Why the apostrophe stands alone?

Hi dama

A little more context would be helpful, however I assume that the word it might refer to some kind of very complicated and/or time-consuming programming. Possibly there is an easier and faster way to do the same thing which isn't 100% "correct", but for amateurs it's good enough because that is all that is usually necessary. So, the word 'overkill' would mean that doing it the 100% correct way is excessive and unnecessary.

I also assume that it' was a typo -- the person probably forgot the letter S (it's).

I really don't know exactly why the author chose to use the word friendly. I'd need more context to venture a guess about that.

This is the entire post of some guy from some forum. It's a discussion which programming language is the best. Somebody said that some programming language is the best for him (it means on c++) and this one is the reply to that.

Hi dama

He apparently thinks that c++ is too (excessively) complicated for amateurs or that c++ is much more than an amateur needs. He might have meant 'user-friendly' when he wrote 'friendly'.
