Sometimes we need to extract a portion of an array data and perform some operation on the extracted data. In Ruby, we can perform such operations with the help of the shift() function.The shift() function takes one argument, which is an index that is used to remove the first element ... Read More

There are chances that we might get some panic while running multiple goroutines. To deal with such a scenario, we can use a combination of channel and waitgroups to handle the error successfully and not to exit the process.Let's suppose there's a function that when invoked returns a panic, which ...

We know that goroutines can be a bit tricky at first, and often we find cases where the main goroutines will exit without giving a chance to the inside goroutines to execute.In order to be able to run the goroutines until the finish, we can either make use of a ... Read More

Whenever we talk about appending elements to a slice, we know that we need to use the append() function that takes a slice as the first argument and the values that we want to append as the next argument.The syntax looks something like this.sl = append(sl, 1)Instead of appending a ... Read More

The standard library of Golang provides a package that we can use if we want to sort arrays, slices, or even custom types. In this article, we will discover three main functions that we can use if we want to sort a slice in Golang. We will also see how ... Read More

Iota in Go is used to represent constant increasing sequences. When repeated in a constant, its value gets incremented after each specification. In this article, we will explore the different ways in which we can use iota in Go.Let's first consider a very basic example, where we will declare multiple ... Read More

When it comes to parsing Date strings in Go, we can use the Parse function that is provided by the time package. In Go, we don't use codes like most other languages to represent the component parts of a date/time string. Instead, Go uses the mnemonic device - standard time ... Read More

In order to be able to understand the anonymous goroutines, we must be aware of the existence of anonymous functions and goroutines. We will first explore the anonymous functions that are the real reason behind the motivation of anonymous goroutines and then we will learn a little about what goroutines ... Read More

We know that substrings are a contiguous sequence of characters in a string, and in order to check whether a string contains a substring, we have two options available.The first approach is to use a built-in function called Contains() and the second approach is to make use a self-written logic ...

The reflect package in Go provides a very important function called DeepEqual() which can be used to compare composite types. The DeepEqual() function is used when we want to check if two data types are "deeply equal".Comparing slicesExample 1Consider the code shown belowpackage main import (    "fmt"    "reflect" ...
