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.

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...
