jQuery library comes in 2 different versions Development and Production/Deployment. The deployment version is also known as minified version. So .min.js is basically the minified version of jQuery library file. Both the files are same as far as functionality is concerned. but .min.js is quite small in size so it loads quickly and saves bandwidth.

jQuery.noConflict
As other client side libraries like MooTools, Prototype can be used with jQuery and they also use $() as their global function and to define variables. This situation creates conflict as $() is used by jQuery and other library as their global function. To overcome from such situations, jQuery has introduced jQuery.noConflict().
jQuery Dollar Sign($)
Dollar Sign is nothing but it’s an alias for JQuery.
Example
$(document).ready(function(){
});
Over here $ sign can be replaced with “jQuery” keyword.
jQuery(document).ready(function(){
});
jQuery Starting Point Of Code Execution
The starting point of jQuery code execution is $(document).ready() function which is executed when DOM is loaded.
Overriding
Overloading in oop is same as overloading in real word. In real word overloading means assigning extra work to same machine or person. In oop method overloading is same. By process of method overloading you are asking your method to some extra work. Or in some cases we can say some different work also.
Normally method overloading in oop is managed on the basis of the argument passed in function. We can achieve overloading in oop by providing different argument in same function.
Overriding in php is very easy. As we know that overriding is process of modifying the inherited method. So in case of inheritance you only need to create method with same name in your child class which you want to override.
Overloading
As we know that we can not implement overloading by creating 2 function in with same name in class. So to implement overloading in php we will take help of magic method __call. Magic method __call invoked when method called by class object is not available in class. So here we will not create method exactly and will take help of __call method. Now call method will provide us 2 argument, 1st name of the method called and parameter of the function. Now with the help of either switch , case or if else we will implement overloading in php.
Delete Database
We can delete a database using DROP DATABASE statement.
Syntax :
DROP DATABASE DATABASE_NAME
Example:
mysql> drop database mage;
Query OK, 459 rows affected (36.63 sec)
Object Oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which are data structures that contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. A distinguishing feature of objects is that an object’s procedures can access and often modify the data fields of the object with which they are associated (objects have a notion of “this”). In OO programming, computer programs are designed by making them out of objects that interact with one another. There is significant diversity in object-oriented programming, but most popular languages are class-based, meaning that objects are instances of classes, which typically also determines their type.
JavaScript Errors
There are three types of errors:
- Load time errors: Errors which come up when loading a web page like improper syntax errors are known as Load time errors and it generates the errors dynamically.
- Run time errors: Errors that come due to misuse of the command inside the HTML language.
- Logical Errors: These are the errors that occur due to the bad logic performed on a function which is having different operation.
Javascript blur Function
Blur function is used to remove the focus from the specified object.
