In Go, a string is a sequence of Unicode characters. Each character in a string is represented by a Unicode code point, which is a unique integer value assigned to each character in the Unicode standard. Runes in Go are simply an alias for the int32 type, used to represent a Unicode code point. In this article, we'll discuss how to check for a specified rune in a Golang string. Checking for a specified rune in a Golang string is relatively simple. We can use the strings.IndexRune function to check if a specific rune is present in a given string. ... Read More

In Golang, checking string equality is a common task that developers come across when building applications. However, when dealing with strings that contain characters with different case representations in Unicode, it can become a little complicated. Unicode case folding is the process of transforming characters to a common case representation to simplify case-insensitive comparisons. In this article, we will explore how to check string equality under Unicode case folding in Golang. What is Unicode Case Folding? Unicode case folding is a process that converts characters to a common case representation to simplify case-insensitive comparisons. In Unicode, some characters have more ... Read More

In Golang, structs are an essential part of the language and are used to define complex data types. Often, you may find yourself in a situation where you need to add a method to a struct to perform some specific action. In this article, we will discuss how to add a method to a struct type in Golang and provide some examples to help you understand the concept. Defining a Struct in Golang Before we dive into adding methods to a struct, let's first understand how to define a struct in Golang. A struct is a composite data type that ... Read More

As a popular programming language, Golang is used in many applications and frameworks due to its high performance and easy-to-use syntax. If you are working with interfaces in Golang, you may need to access the fields of the interface to retrieve or manipulate data. In this article, we will discuss how to access interface fields in Golang and provide some examples to help you understand the concept. Understanding Interfaces in Golang Before we dive into accessing interface fields, let's first understand what interfaces are in Golang. An interface is a set of method signatures that define a behavior. In other ... Read More

Splitting a string after a specified separator is a common operation in many programming languages, including Golang. In Golang, the strings package provides several functions to split a string after a specified separator. In this article, we will discuss how to split a string after a specified separator in Golang. Using strings.SplitAfter() The strings.SplitAfter() function is used to split a string after a specified separator. It takes two arguments: the string to be split and the separator after which to split the string. The function returns a slice of strings. Example Here's an example code that demonstrates how to use ... Read More

In Golang, there are multiple ways to split a slice after a specified separator. This can be achieved using built-in functions and methods. In this article, we will explore some of the common ways to split a slice in Golang. Using strings.SplitAfter Function The strings package in Golang provides a SplitAfter function, which splits a string or slice of bytes after the specified separator and returns the result as a slice of strings Example package main import ( "fmt" "strings" ) func main() { slice := []string{"apple_", "banana_", "cherry_", ... Read More

In Golang, slices are used to store sequences of elements of the same type. Slicing a slice is a common operation in Golang, but sometimes we need to split a slice based on a specified separator. Golang provides a built-in function to split a string based on a separator, but splitting a slice is a bit different. In this article, we will explore how to split a slice separated by the specified expression in Golang. Using the Strings Package The strings package in Golang provides the Split() function, which is used to split a string into a slice based on ... Read More

In Go, comparing two slices of bytes involves checking if each element in both slices is equal. This can be done using a loop or the built-in bytes.Equal() function. In this article, we'll explore both methods and see how to compare two slices of bytes in Go. Using a Loop To compare two slices of bytes using a loop, we can iterate over each element in both slices and check if they are equal. Here is an example − Example package main import ( "fmt" ) func main() { slice1 := []byte{0x01, ... Read More

In Golang, it's common to work with time-related operations, such as comparing times. Comparing times is essential when dealing with scheduling, deadlines, and many other scenarios. In this article, we'll explore how to compare times in Golang and provide you with a comprehensive guide. Golang Time Package Golang provides a built-in time package, which offers various functionalities related to date and time. To use this package, you'll need to import it in your code using the following syntax − import "time" The time package provides a Time type that represents a specific time. You can create a Time value ... Read More

When working with Go, it's often necessary to compare structs to determine whether they're equal or not. Comparing two structs can be easy when they have the same values assigned to their data fields. However, comparing structs with different values assigned to their data fields can be a bit more complicated. In this article, we'll discuss how to compare structs with different values assigned to their data fields in Golang. Comparing Structs with the Same Values Assigned to Data Fields Before we dive into comparing structs with different values assigned to their data fields, let's first take a look at ... Read More
