Haskell Course:-
The World of Haskell Programming:
Haskell Programming was named after Haskell Curry who was a logician. If you are good in Math, then probably you will find Haskell much easier to learn. For example say, in an imperative programming language like Python or C, you can say in the start like:
X=1x=X+1print x till x<10
The above is just a pseudo code for calculating the sum from 1 to 10. Thus I have used here x as one in the start, then increase the value by one every time using a loop till x is less than 10.
Through this Haskell Course you will learn that, every function in Haskell Programming is based on Mathematics. Most of the applications and problems are based on the To-prove theorem. In other languages, where you find the statements, you won’t find the same in Haskell.
Through this Haskell Course you will learn that,, Haskell programming is more based on logic and structure. Unlike other programming languages like say Ruby or Perl, Haskell helps to write properly indented code which makes it simpler and easier to read and cleaner to write.
About this Haskell Course:
This Haskell Course will be using the GHCI compiler and notepad++ for solving problems. This Haskell Course is not for absolute beginners. This Haskell Course will take you through the basics of Haskell.
Through this Haskell Course you will learn that, already having knowledge about the terminologies of a programming language might prove helpful. Haskell offers lazy style computing. Though Haskell programming is more of a statically typed programming, this course will also pick up examples on dynamically typed codes.
This Haskell Course will cover the basic theorems, algebra, sets and unions in Mathematics. The Haskell version used is v7.10.2-a and will be run in a windows environment.
Through this Haskell Course you will learn that, Haskell programs require lots of modules to be imported, some which are not easily available online. Most of these modules since are hard to find, the codes for them will be covered in the Notepad++ instead of executing it directly in the GHCI compiler.
Haskell Course Pre-requisites:
Haskell Course doesn’t have a specific pre-requisite as of such. Knowing basic terminologies of programming languages such as functions, arguments, statements and conditions, will help you get around and in getting started with Haskell.
Though C and Java are way too different from Haskell, knowing them might help in getting used to the concurrencies and garbage collection. Haskell has its own way of doing things, and when I say own way I mean the lazy way.
If you have any experience in programming previously, then you may find a lot of shortcut ways taken in Haskell programming.
And these so called ‘shortcuts’ are not just shortcuts but the actual way of coding in Haskell. Another specific pre-requisite for learning Haskell might be to have a good understanding of Algebra and Geometry in Math.
They will help you to get around understanding Haskell theorems in a much easier manner.
Haskell Course: Haskell Packages
Through this Haskell Course you will learn that, one thing worth making note about is that the default GHCi comes pre-loaded with a bunch of packages. To check the packages installed, one can simply do it in the interpreter by typing $ ghc-pkg list.
However, one can even install the packages separately by using the Cabal. Cabal is a system infrastructure for configuring and building packages and libraries for Haskell.
Using command line flags, one can change the visibility of packages to either exposed or hidden. By default, GHC only allows to import the exposed packages. If you try to import any hidden package, the compiler will return an error message. Every application in Haskell must define a main inside the module in every main package.
Whenever you are trying to import a module, make sure you have checked the hidden packages for the modules with the same name or config, else you may end up having multiple modules which do the same thing and they may overlap each other.
In this Haskell Course, you will learn that, every package which is installed has a UID i.e. the unique identifier. This unique ID stands for the package ID so as to differentiate it from the rest.
Who should learn this Haskell Course?
Haskell programming proves it’s worthwhile to a lot of people. Every programmer who has learnt C, Java, Python or assembly should learn Haskell. The main reason being Haskell is a functional based programming language. I could actually give you a list of people who would need to learn Haskell Course:-
Advanced Mathematics and proving general scientific theorems can take up this Haskell Course.
The main reason behind this is because Haskell is purely based on logic, which sometimes seems to lack in languages like Python or Ruby. For example, a lot of things or I would prefer the official term ‘magic’ happens in Python. If you want to do something, just import it and it happens.
As a matter of fact, Haskell programming can be a rock solid foundation for a programmer as the first learning language. Let me give an example. In usual programming, we use loops and conditions.
But in Haskell, we have to generally find some other viable options such as the maps, folds and filters to get around the problem. This helps people to solve a problem in more than just one way and it opens up the various approaches one tends to have towards a problem.
This makes you a more reasonable programmer and to switch viewing angles when needed towards solving a complicated problem. I often find myself solving problems of C and C++ in Haskell, which if I would have stuck with C or Java wouldn’t have been able to solve with.
Why learn this Haskell Course?
Most of the answers to this question as to why to learn this course have already been answered previously. But still let me get this a bit clearer. Haskell is prefers lazy evaluation for solving problems. Let me give you a simple example to differentiate between Haskell and C.
Now the above codes are written to copy the contents of one file and write it to the other file. You can easily see the difference between the amounts of time one may require to write both of the codes since the code of the Haskell is pretty up to the point and short as well.
Okay, let’s say we leave the topic of writing smaller codes since even a python file can even do that. Then how is this different from that of a python? Now the answer to this as I said previously is lazy evaluation.
In Python or C, the whole program will be loaded into the memory and then it will get executed. But that’s not the case with Haskell programming. In Haskell everything is lazy here. I would more prefer to call it smart rather than lazy, but since lazy is the official term, be it as it is.
Learning Haskell leads to better design structure and reduces the chances of errors and bugs due to logical programming. The codes written are quiet compact similar to that of Python, but at the same time as efficient as that C such as being fast.
And Haskell functions have no side effects since one function does a job only within itself due to referential transparency.
What really sets Haskell different from any other languages is its logical reasoning and if brainstorming is what you are looking for, then Haskell programming it is that you need to learn.
Real World Applications of Haskell Course:
Now if you are still reading this article, this means you haven’t given out hope yet and you also know that you cannot use Haskell to write automated codes for your daily jobs on the go, which you can for Python, Bash or Ruby. But Haskell was not meant for that.
Haskell is used a lot in industry, but not as much as C, C++ or Java. But let’s take a look as to what Haskell Course can actually be used for by the industry in the real world.
In this Haskell Course, you will learn that, due to its logical reasoning, Haskell programming is most often used in banking sectors for calculating out huge investment tasks.
