![]() ![]() In the example below, you see some booleans. The boolean data type is pretty much as straightforward as other data types. The output will be: "Hello Medium" :: Īs I already said, a string is just a collection of characters, so this will be returned as a Char data type. If want to know the type of this string, we can use :t again: Prelude> :t "Hello Medium" We can create the following string: Prelude> "Hello Medium" To display the type of a variable, you can enter the following line of code: Prelude> :t "a"Ī string is nothing but a collection of characters. Like numbers, Haskell can intelligently identify a character given as an input to it. Therefore, you need not mention its type externally as we usually do in other programming languages. Haskell is intelligent enough to decode some number as a number. Take a look at the following code: Prelude> main = putStrLn "Hello Medium" It is a simple example to demonstrate the dynamism of Haskell. Now, you can enter your Haskell code, for example: Example program It’s effortless to start the Haskell programming language, and you enter the following command in the terminal: $ ghci To set up a Haskell environment on your MAC system, go to their official website and download the Mac installer.įor Linux, the installation process is as follows: $ sudo apt-get install haskell-platform To set up a Haskell environment on your Windows computer, go to their official website and download the installer. Hence we need not explicitly mention the style of the variable used.– By the term strictly typed language, we mean the Haskell compiler is intelligent enough to figure out the type of the variable declared. Also, Haskell is a sluggish programming language, so the program doesn’t execute code that it thinks is not necessary.Ī Haskell program is nothing more than a series of functions that execute. That’s not so in Haskell, where we ask what it is we do. In typical programming languages, we instruct a compiler to do something and how to do it. Haskell is a widely used purely functional language.įunctional programs are more concurrent, and they follow parallelism in execution to provide more accurate and better performance. This is a beginner’s tutorial to let them understand the fundamentals of Haskell. Haskell is a functional programming language that has been specially designed to handle symbolic computation and list processing applications ![]()
