We can use conditional rendering to only display the spinner when certain conditions are met, such as when data is being fetched from an API. Additionally, we can use CSS to style the spinner and make it match the overall design of our website. What is NextJS? Next.js is a JavaScript framework for building server-rendered React applications. It provides a set of features and tools that make it easy to build and deploy high-performance web applications, such as automatic code splitting, server-side rendering, and static site generation. Next.js also simplifies the setup process and provides a development environment that allows ... Read More
What is String Concatenation? In Go, string concatenation is the process of combining two or more strings into a single string. There are several ways to concatenate strings in Go. We shall discuss them in this article. Method 1: By Using User-Defined Function The function that we create will take two strings as arguments and will return the resultant string by combining both of them as the result. Algorithm Step 1 − First, we need to import the fmt package. Step 2 − Then create a function that will join the two strings together. The function accepts two ... Read More
In the go programming language, there are several types of special escape sequence characters. Usage of each one of them implements a different type of functionality. We shall discuss each one of them one by one in the upcoming examples. Example 1 In this example, we will write a go language program to demonstrate the backlash (//) character. It is used to display a slash in the output of the program. package main import "fmt" func main() { fmt.Println("Program to display a backslash using in the program") } Output Program to display a backslash using in the program\ ...

In Golang there are various techniques of printing double-quotes in the string. In this article, we are going to learn those techniques with various example. Syntax func Quote(s string) string Quote() function is present in strconv() package and is used to add a given string literal in double quotes. The function accepts the string variable that is to be quoted as an argument and returns the string after adding double quotes to it. func Sprintf(format string, a ...interface{}) string This function returns a formatted string. It takes a number of arguments in string format. The first argument should ... Read More
What is string in golang? In Go, a string is a sequence of characters. It is an immutable data type, meaning that once a string is created, it cannot be modified. Strings are enclosed in double quotes ("") and can contain any combination of letters, numbers, and symbols. They are commonly used to store text and are often used as input and output in programs. Method 1: By Using An External Function In this method, the function that we create will accept the string whose length is to be calculated as an argument and returns the final length of the ...

In Golang, there are various methods to get characters from a string with the help of an index. In this article, we are using external functions as well as by using internal functions defined in the go language. Method 1: Using User-Defined Function In this method, the function that we create will take the string whose character is to be determined along with the integer type index of the string and will return the character of the string present at that index. Algorithm Step 1 − First, we need to import the fmt package. Step 2 − Then, create ... Read More
An Armstrong number, also known as a narcissistic number, is a number that is equal to the sum of its own digits each raised to the power of the number of digits. Here we will show different approaches about how we can print the Armstrong numbers in go programming language. Method 1: By Using Math Package In this example we will use different functions present in math package in order to print the Armstrong numbers between said limits. Syntax func Pow(a, b float64) float64 The pow() function is present in math package and is used to raise one number ... Read More
In go language, a long is not a separate data type but it is an extension made from the integer data type to store even larger values of integers. The main difference between an int data type and long data type is that an int data type is 32 bits whereas long data type is 64 bits. Here we will learn about different techniques to convert long types variables to int using go programming language. Method 1: By Using Type Casting In this example we will use the type casting approach to convert the long data type variables to int. ... Read More
We can add a shadow to a canvas circle using Fabric.js by creating a new circle object, then setting the "shadow" property of the object to an object containing the desired shadow properties such as color and offset. Fabric.js is an open-source JavaScript library that allows developers to create and manipulate HTML5 canvas elements with ease. It simplifies the process of creating, editing and animating canvas elements by providing a set of powerful and flexible APIs. With Fabric.js, developers can create complex canvas graphics, animations, and interactive elements without having to deal with the low-level canvas API. It also provides ... Read More
A substring in Go is a portion of a larger string. It is specified by providing a start index and a length, and it contains the characters of the original string starting at the start index and going up to the specified length. The characters in a substring are still a part of the original string and share the same memory. In Go, a string is a sequence of characters. It is an immutable data type, meaning that once a string is created, it cannot be modified. Strings are enclosed in double quotes ("") and can contain any combination of ... Read More
