In this example, you will learn about JavaScript arrow function. Arrow function is one of the features introduced in the ES6 version of JavaScript. It allows you to create functions easy way compared to regular functions. Regular Function // regular function let result = function(a, b) { return a + b; } ES6 Arrow Function // arrow function let result = (a, b) => a + b; Arrow Function Syntax The syntax of the arrow function look like is: let myFunction = (arg1, arg2, ...argN) => { statement... } Here, myFunction is the function name arg1, arg2,...argN is the argument(parameter) of the function statement... is the body of the function

How to Remove Specific Element From An Array In this example, you will learn to write a JavaScript program that will remove a specific element from an array. Example 1 : Using For Loop Remove Element From Array function removeElementFromArray(array, n) { const newArray = []; for ( let i = 0; i < array.length; i++) { if(array[i] !== n) { newArray.push(array[i]); } } return newArray; } const elements = [1, 2, 3, 4, 5]; const result = removeElementFromArray(elements, 4); console.log(result); Output [1,2,3,5] In the above program, an element 4 is removed from an array using a for loop. Example 2 : Using Array.splice() Remove Element From Array const elements = [1, 2, 3, 4, 5]; //remove element 3 const result = elements.splice(2,1); console.log(elements); Output [1, 2, 4, 5] In the above program, an element 3 is removed from an array using a splice() method.

What is ASP.NET Core? ASP.NET Core is a web framework created by Microsoft for building web applications, APIs, and microservices. It uses common patterns like MVC (Model-View-Controller), dependency injection, and a request pipeline comprised of middleware. It's open-source under the Apache 2.0 license, which means the source code is freely available, and the community is encouraged to contribute bug fixes and new features. ASP.NET Core runs on top of Microsoft's .NET runtime, similar to the Java Virtual Machine (JVM) or the Ruby interpreter. You can write ASP.NET Core applications in a number of languages (C#, Visual Basic, F#). C# is the most popular choice. You can build and run ASP.NET Core applications on Windows, Mac, and Linux. Why do we need another web framework? There are a lot of great web frameworks to choose from already: Node/Express, Spring, Ruby on Rails, Django, Laravel, and many more. What advantages does ASP.NET Core have?  Speed . ASP.NET Core is fast. Bec

This article demonstrates how to import the data from a Microsoft Excel sheet to a SQL Server table in Microsoft SQL Server. Let’s start step by step. Here I have one Excel sheet with employee details data with six columns as above and this detail I will use as an example and load into employee table.  Open SQL Server management studio and run following SQL query. DECLARE @Qry NVARCHAR(MAX) DECLARE @FilePath NVARCHAR(255)='D:\Employee.xlsx' EXEC sp_configure 'Show Advanced Options', 1; RECONFIGURE; EXEC sp_configure 'Ad Hoc Distributed Queries', 1; RECONFIGURE; SET @Qry='SELECT * FROM OPENROWSET(''Microsoft.ACE.OLEDB.12.0'', ''Excel 12.0; HDR=yes; Database='+CONVERT(NVARCHAR(255),@FilePath)+''', [Sheet1$]);' INSERT INTO Employees EXEC (@Qry) select * from Employees You have to make sure "Microsoft Access Database Engine Redistributable" is install or not in your local machine.

A SQL JOIN is used to combine two or more tables, based on a related column between tables. Let's take a look selection from the "Orders" table: OrderId CustomerId OrderDate 1001 1 2020-05-22 1002 2 2020-05-22 1003 3 2020-05-22 Then, look at a selection from the "Customers" table: CustomerId CustomerName Country 1 John USA 2 Bill USA 3 Jimmy USA Now, the relationship between Orders table and Customers table is the "CustomerId" column. Then, we can create the following SQL statement that contains an INNER JOIN, It'll select records that have matching values in both tables: SELECT o.OrderId, c.CustomerName, o.OrderDate FROM Orders as o INNER JOIN Customers as c ON o.CustomerId=c.CustomerId and above SQL statement will produce following result like this: Orde

C# can be used in a window-based, web-based, or console application.
