Scalable Vector Graphic, sometimes known as SVG, is a type of 2D graphic or image file. In order to create visuals, SVG files employ mathematical formulas and a set of guidelines about shapes, lines, and other features. SVGs are simply XML code that specifies how colours should be presented, where each form should appear in respect to other shapes inside a file, and how shapes should be displayed. SVGs and some other vector graphics were significantly different than raster graphics that depend on pixels to convey visual data, like jpegs or png files. The four advantages of using SVG files ...

Throughout this tutorial, you will learn about the higher-order functions available in Swift. You will find out what they are used for and how to use them. What are they? A higher-order function is a function that takes one or more functions as arguments or returns a function as its result. Below are the higher-order functions provided by the Swift language − forEach() map() compactMap() flatMap() filter() reduce() sort() sorted() All the higher-order functions are based on closure but don't worry you don't need to be a master of closure. They are easy to use and also reduce ... Read More
In touch devices, an element sticks when a hover effect is added to it using CSS. This article will teach us how to deal with this problem.

Only hover-enabled devices will see the added hover effect; touch ... Read More
In this tutorial, you will learn how to improve code readability in the Swift language. You can follow a variety of techniques when writing code. By following these methods, you will be able to write more understandable code for yourself and other developers. Use Comments This is the most important thing we should do. When writing code, we often write logic and calculations. When we start, we have everything in our minds, but after a month, it's definitely difficult to remember everything, especially in large applications. The code is usually commented on single lines. As a result, we are better ... Read More
In this tutorial, you are about to learn how you can use generics to make your code reusable and flexible in an application. You will see how to create functions and properties that can work with any type with an example. What is generics? Swift allows you to write flexible, reusable code using generics. Generic code can work with any type. You can write code that avoids duplication and expresses its intent in a clear, abstract manner. Generics are one of the most powerful features of Swift, and much of the Swift standard library is built with generic code. You’ve ... Read More
In this tutorial, you will learn the use of double question marks (?) in the Swift language. In Swift, a double question mark (??) is called the "nil−coalescing operator". This operator is basically used to provide a default value in the case of nil. In other words, when a variable is nil and you want to provide a default value in the absence of a value, use this operator. According to Apple documentation The nil-coalescing operator (a ?? b) unwraps an optional a if it contains a value, or returns a default value b if a is nil. The expression ... Read More
This guide will cover what classes and functions there are in the Swift programming language. Also, what are the differences between them? Most of the time, when we write code in a project, we have to deal with classes and structures. It is true that these two features are the most significant in Swift. In a real−time application, whatever you want to write, you need to create a class to assign responsibility. If we already have a class option, we need to understand why and when we should use the structure. Structures are one of the fundamental concepts in the ... Read More

When a user wishes to paste something into an input field, they have two options: either they can use the context menu by right-clicking on the webpage or they may use their keyboard by pressing the CTRL and V buttons simultaneously. The keydown event's ctrl attribute is used to figure out the key combination that contains "Ctrl."
