Javascript-IIFE-(3)

👉IIFE


✅Immediately invoked function expression

IIFE is used when you want to create the function and at the same time, if you want to invoke the function.

Since you don't want to invoke the function later in the script, it's not required to give a name to the function. 

This function gets created and executed right away. This is also termed an anonymous function.

To generalize,  IIFE is used when you want to execute start-up code in the script, or code is specific to that page, or code is for one-time use and not used anywhere else in the script.

(function () {alert ("hi"); } () );

   👉 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...

To create a target table without the records from the source table, the SELECT statement must have a WHERE clause. The WHERE clause must specify a condition that cannot be specified. 👉 Inserting data into a table from another table It is used to populate a table with data that already exist in another table. 👉DELETE Command The DELETE command deletes the rows from the table that satisfies the condition and returns the number of records deleted.
