  Passing Arrow Functions vs Attaching Arrow Functions in JavaScript While learning JavaScript arrow functions, I came across the terms passing an arrow function and attaching an arrow function . At first, these concepts seemed similar, but they describe two different things: Passing a function as a value to another function (callback) Attaching a function to an object as a method This article explains the difference with examples. What are Arrow Functions? Arrow functions were introduced in ES6 (ECMAScript 2015) . They provide a shorter syntax for writing functions. The traditional way of writing a function: function add ( a, b ) { return a + b; } The same function using an arrow function: (a, b) => a + b; Arrow functions are especially useful when working with callbacks because functions in JavaScript can be passed around as values. Passing a Function (Callback Function) Passing a function means giving a function as an argument to another function. function add ( a, b ...

Introduction In C# class is a blueprint for creating objects. It contains data (properties) and behaviour (methods). We can build multiple objects with distinct properties and methods using classes without having to repeat the code. Class Syntax: Creating a generic C# Class public class Car //car is the class name and Pascal case { public string Model { get; set; } //properties public string Color { get; set; } public void Start() //method { Console.WriteLine("Car started."); } public void Stop() //method { Console.WriteLine("Car stopped."); } } A generic class in C# is created using a class keyword followed by class name. Class name, property name, method name must always be Pascal case i.e. Starting letter must be capital case. Class can have different properties and methods. We cannot use the class directly without creating an object. In order to use class we must create an object which is an inst...

C# DateTime is a value type (struct) that represents a specific date and time. It's found in System namespace. This feature comes in handy whenever we need to work with date and time. We can create or instantiate a DateTime object as follows: DateTime date = new DateTime(2019, 03, 29, 15, 0, 0); In the above example year, month, day, hour, minutes and seconds have been provided as an argument. If we print date using Console.WriteLine() then  it will show following output.  Console.WriteLine(date) //-->/29/2019 3:00:00 PM We can also use the same principle to create a DateTime object representing the current date and time DateTime now = DateTime.Now; We can compare the two dates if (date > now) { Console.WriteLine(true); } else Console.WriteLine(false); Above example prints false as the date is smaller than the now. We can also format DateTime object as per our requirements. An example static method is shown below public static string Description(Dat...
