👉Types of triggers

✅Row Triggers:
A row trigger is fired once for each row that is affected.
If the triggering statement affects no rows, the trigger is not executed at all.

A statement trigger is fired once, independent of the number of rows the triggering statement affects.

✅Before Triggers:

   👉 Javascript with OOPs (Inheritance) In Javascript, Inheritance is done using prototype object. A prototype object is an object pointing to another object. We don't have a direct inheritance in Javascript, we can mimic inheritance using prototype. Let's say, we have one more class that inherits from Customer, and it submits to Server2. function CustomerChild(){         this.submit = function() {         alert ("this submits the data to Server2" + " "      +  this.CustomerName + " "                                       + this.CustomerCode");   }}             CustomerChild.prototype = new Customer(); var cust = new Customer(); cust.CustomerName ("John"); cust.Submit();  --this is a call to the submit method of the Customer class.  cust = new CustomerChild(); cust...

Unobtrusive javascript seperates presentation from behavior, making HTML more sleek. <input type = "button"  id = btn1/> <script src = "jscript1.js" type = "text/ javascript"> </script> code of jscript1.js file: <script language = "javascript">            Function Fun1() {                      alert("Hi");             } var e1 = document.getElementByID("btn1"); e1.onclick = ...
