5 min readMonads are a fundamental concept in Haskell that allows you to handle effects, perform computations, and manage state in a purely functional way. They provide a way to encapsulate and sequence operations, allowing you to compose complex computations from simpler ones.To use monads in Haskell, you first need to understand the basic idea behind monads. A monad is a type that defines two main operations: return and bind.

10 min readChannels in Go are a fundamental feature that enables communication and synchronization between goroutines, which are lightweight threads. Goroutines can communicate with each other by sending and receiving values through channels.To use channels for communication between goroutines in Go, you first need to create a channel using the make function. This is done by specifying the type of the values that will be passed through the channel.

7 min readType classes in Haskell are a powerful mechanism for defining and enforcing behavior across different types. They allow Haskell to achieve ad hoc polymorphism, which means that different types can be given the same behavior even if they are unrelated by inheritance or interfaces.To define a type class, you use the class keyword followed by the class name and a list of type variables.

7 min readIn Haskell, data types are used to define new types of values. Defining and using data types is an important aspect of the language as it allows programmers to create their own custom types.To define a data type in Haskell, you use the data keyword followed by the name of the type. This is typically done in a separate module or at the top level of the Haskell file.

9 min readIn Haskell, input/output (I/O) operations are performed using the IO monad. The IO monad is a special type that encapsulates the execution of I/O actions, allowing for the sequencing and composition of these actions.To perform an I/O operation, you define an action that describes what needs to be done. The action can involve reading from or writing to files, interacting with the user through the command line, or performing any other kind of I/O operation.

7 min readConcurrent programming in Go is made easy with goroutines, which are lightweight threads used for concurrent execution of code. Here are some key aspects to handle concurrent programming in Go:Goroutines: A goroutine is a lightweight thread managed by the Go runtime. You can start a new goroutine with the keyword "go" followed by a function call. Goroutines are highly efficient and can be created in large numbers without overwhelming system resources.

6 min readRecursion is a fundamental concept in Haskell programming and is widely used to solve problems that can be broken down into smaller, similar subproblems. In Haskell, recursion refers to a function that calls itself during its execution.To use recursion in Haskell, you typically define a recursive function by specifying a base case and a recursive case.

6 min readIn Haskell, lists are a fundamental data structure used to store sequences of elements of the same type. The elements of a list are enclosed within square brackets and separated by commas. Lists are immutable, meaning once created, their elements cannot be modified. There are various functions and operators available in Haskell to work with lists:Creating Lists: An empty list: []. A list with elements: [1, 2, 3]. Using a range: [1..10] creates a list from 1 to 10.

7 min readIn Go, an interface is a collection of method signatures. It defines a set of behaviors that a type must implement. To implement an interface in Go, you need to provide method implementations for all the methods defined in the interface.To implement an interface, follow these steps:Define the interface by listing the required method signatures. For example: type Writer interface { Write([]byte) (int, error) } Create a new struct type that you want to make implement the interface.

5 min readPattern matching is a powerful feature in Haskell that allows you to destructure and extract information from data structures. It allows you to define functions and expressions based on different patterns that the input can match. Here's a brief explanation of how to use pattern matching in Haskell:Function Definitions: When defining functions, you can use pattern matching in the function definition. Each pattern corresponds to a specific input case.
-
4 min readIn Haskell, functions are defined using the keyword "let" followed by the function name, a list of arguments, an equal sign, and the function body. The function body specifies what the function does when applied to its arguments. Here's the general syntax:let functionName arg1 arg2 ... = functionBodyThe arguments are separated by spaces, and the function body can be any valid Haskell expression.
