Are function arguments lazy evaluated? Meaning if a function argument is a function with arguments say funcA, is the evaluation of the argument funcA delayed until it's needed?

Thanks

That's exactly right! For the most part, nothing in Haskell is evaluated until it is absolutely needed (which can often be surprisingly deep into a program). For most of Units 1-3 this is not going to have a major impact on how you write code. In Unit 4 we discuss when this become tricky and provide a couple of solutions.
