There may be instances in Golang where the execution of different goroutines may cause unexpected behaviour. In such cases, we want to make sure that certain goroutines work in a predefined manner and the program waits for all goroutines that are launched from the main function to wait. To do ... Read More

In order to understand why mutex in Go play a significant role to write better and accurate concurrent programs, we must first be aware of the concept called Race Conditions. Let's first understand what Race conditions are and how we can write a concurrent program that features a race condition ... Read More

There are often cases where we would want to perform a particular task after a specific interval of time repeatedly. In Golang, we achieve this with the help of tickers.We can use them with goroutines as well so that we can run these tasks in the background of our application ... Read More

Reflection in Golang is about getting to know the data types of the data that we are dealing with at runtime. There are often certain scenarios where we would want to know the data type of a certain variable that we are getting at runtime or something similar.With the help ... Read More

Before discussing signals and how to handle them, let's talk about a common scenario of creating a signal. A signal can be passed from the terminal, by either terminating the program with the help of CTRL+C or we can by default call the Exit() function that the os package provides ... Read More

Timeouts play an important role when we don't want to wait for the output for some goroutines that are taking more time than what they should take. It should be noted that Go directly doesn't support timeouts, but we can implement them without any difficulty.Let's suppose we have a case ... Read More

In this article, we will see the differences and similarities that are there between a slice that is declared as an empty and a nil slice.Slices in Golang are used to store a sequence of elements. Slices can be expanded at any time and they are declared in the same ... Read More

In this article, we will learn what similarities and differences are there between functions and methods in Golang. We will start with each of them separately, and then we will see an example where both of them will be used.Let's start with functions and see what they are and how ... Read More

We can make use of channels if we want to synchronize goroutines. By synchronizing, we want to make the goroutines work in a defined manner, for example, not starting the next goroutine until the previous one has finished its execution.The channels help in achieving that, as they can be used ...

Response status codes are the numbers that we get in response that signify what type of response we received from the server when we asked for something from it.There are different status codes that one gets from the response, and these are mainly divided into five categories.Generally, the status codes ...
