You’ll learn everything from functional programming concepts to the applications of this paradigm.
Here we cover functional programming languages and example languages. One of these is functional programming, which has a strong mathematical foundation to it. There are several kinds of programming paradigms, each with its own purposes and advantages. Functions are First-Class and Can be Higher-Order
WHAT IS HASKELL FUNCTIONAL PROGRAMMING CODE
This makes it a natural fit for functional programming, because it makes working with very natural, intuitive functional idioms appropriate for a wider problem space than you can get away with in strict languages, where specific constructs that complicate the code are necessary to defer evaluation e.g. you don't need any specific mechanism for implementing generators or iterators, you can just write a recursive function that builds a list, and the items will be generated one at a time on demand.
Lazy evaluation also makes various types of code easier to write, e.g. Lazy evaluation depends on the language being purely functional for correctness, otherwise it becomes impossible to reason about the order of side-effects, so writing any non-trivial program in a non-pure lazy language is essentially impossible. I don't tend to think of lazy evaluation separately from the functional nature of Haskell. I see many tutorials that include advanced features (eg typeclasses, use of monads other than for the purposes of IO) at an early stage of learning, but I think learning the basics of the functional paradigm first in this more restricted environment could be very helpful for a beginner. This subset of Haskell is slightly more powerful than Miranda (the Prelude contains better IO facilities than Miranda had, and Miranda only had a single numeric type), and is therefore adequate for writing many useful programs, but is somewhat easier to learn than the entirity of Haskell, which has grown to be quite a large language. The standard functions defined in the Prelude, except generic uses of Monads (IO is the only monad a beginner should need, and only simple features of it Lists, Maybe and Either should be treated as standard data types, and not used as monads). My main takeaway from this is: you can write non-trivial programs in the subset of Haskell that was inherited from Miranda, and doing so could be a useful educational exercise. Haskell was essentially designed as a superset of Miranda its syntax and semantics are very similar for the features shared between them, but Haskell adds a lot of additional features (eg type classes, modules, do blocks for writing sequential code, and so on). I originally learned FP at University back in the 90s, using a language called Miranda, which I think was a good choice at the time (Haskell was around by then, but probably wasn't a good choice as there were no textbooks available using it at the time).
