Coding my first Server

Todays Learning: 
Today I had a lot to learn and it gave me a glimpse of how web works behind the scenes and what local host is and how to make your system as a server. 

1. Express is a server side javascript framework used along with node. 
2. A server with Express is created via the following steps: 
. Create a directory
. Create index.js file
. Initialise npm
. Install express package
. Write server side logic
.start server. 
3. Https - protocol used between the communication of client side and server side.
4. GET, POST, PUT, PATCH and DELETE
5. Used Express to create my first server where I just displayed Hello World with app.get request!!
6. HTTP status codes.

The third parameter - Event bubbling and Event capturing

I have been learning about events in JavaScript lately. I stumbled upon a very popular topic and learned something new that I wanted to share. It's about event bubbling and event capturing. As you can see, I have created a ul element with 5 images listed under it, each inside li elements. I've also added corresponding IDs to target each image and the ul element. __________________________________________ In the above code, one event listener targets the ul element as a whole. Whenever an image inside the ul element is clicked, the event fires, and it is logged in the console. Notice that the third parameter is set to false. Secondly, there's another event listener that gets triggered when the specific target sheep image inside the ul element is clicked, logging the corresponding message. Now, note that the third parameter in both events is false, leading to two consequences: Case 1: Event Bubbling (3rd parameter: false) When an image inside the ul element is clicked (other ...

Binary Sreach Algorithm : Optimized way to get the index of the mid element

The classical way to find the mid element in an array would be (start+end)/2.  But integershave a limited range and what if the size of the array is too large and (start+end) exceeds the range of integers in java?? Hence, inorder to make optimize it I learnt a new way to find the mid element which is  start + (end-start)/2 in this way, even if the size of the array exceeds the integer range, the end-start would make it smaller.

Abstract classes

I have been learning the most important concepts of java which is the object oriented programming and today I learnt about the abstract classes and method and wanted to share my thoughts on them.  Abstract method : Method which doesn't have a body is said to be an abstract method and also it is declared using an abstract keyword.  Abstract class : If a class contains an abstract method, then it is termed as an abstract class and it should also be declared with the abstract keyword.  The fun part :  Abstract classes are like a template or a thought. It has abstract methods but no definition. When a child class extends (inherits) this abstract class, the abstract class allows the child class to over ride it in its own way.  For example, if an abstract class has an abstract method known as greet(), then the child class can override it in its own way like greet() can now say good mrng or good afternoon.  Note :  1. Objects of abstract class cannot be insta...
