The Basics of Javascript

If you are writing big code it is very helpful write comments to the segment of the code as comment will not be executed, it is for codemasters to check where and which segment is located. Learning HTML is not the sole discretion of programmers as the trend can be seen it is been learnt by many bloggers and webmasters.

The sole purpose for this is to make it more and more convenience and to customize the web page to its fullest extent all by it self as with this knowledge in your kitty , you can reduce the cost factor as you can make the coding and with the advent of modern web technologies . With the advance modern web , where you can find more and more use of API and other related applications and with due course of time even the web page is fast becoming one of the conglomerate of applications visibility.

JavaScript is a scripting language and it is funnily called as diet programming language because of its easy in nature and the way it can be employed with very slight nature of use and appliances. It is been designed for easy to learn and adopt and it is wonderful for novices. It is also true that you can learn and can code the language within short span of time; it is very easy to use and adopt. It is a good practice to learn the basics of NTML before learning the basics of JavaScript. In the later time I shall write the details of HTML and the points which you should know about it.

How Java Script works:

Java and Java Script share the names only but these two languages have very little in common, in fact there are vast differences between these two languages. JavaScript is the language which meant to introduce the very basic elements of web and it is solely based in web and it works in cloud. Java is the language which tends to work as desktop application and in many big enterprises and also it goes on with to work online with various databases and its scope is very high and it does related with many applications and platforms simultaneously.

Java script is an interpreted languages and the browser interprets it and processed all the information in real time by contacting all server files and then interpret and shows it on your web page.  You can change the value of variables at any time s the name suggests it is dynamic in nature; all variables need a declaration – that is you have to tell the interpreter what to treat as variable.

Functions are blocks of code, once written can be used as many times as declared within the program. If you want to add the functionality of Add and Print, then you could write a function called AddAndPrint and so on. It is useful for more complex coding as it can supplement easily for hundreds lines of code and that can reduce the overall size of the code.

As JavaScript is always at the interpret side and works with browsers so minimization holds the key as if its size is very small then it would not affect the vital page load time and in this way you can have some of the added functionality plus search engine optimization and page rank settings. Many JavaScript in the web page can reduce the page load time, thus makes heavy the site and also it affects your site with Google Panda updates and for this it is vital in nature, as it can affect Google’s search front page.

That is why, it is good to use functions if you are using and coding long and in this manner it does makes the code small and precise. Object, in programs represent physical entitles, complete with their attributes and behaviours.  The objects you will encounter when writing Java Script code will include the browser window- you can use the command to open the window. Everything else is also an object- be it text boxes, images, even your mouse cursor.

Java Script code is always enclosed in the <script> tags inside your HTML document. You can insert code blocks anywhere in the document, but it is always good practice to enclose your script within the <head> tags of the HTML. This way, the script will always be loaded before it gets used within the page. There are no semicolons at the end of each line. They are purely optional, and there so that C programmers do not suddenly feel out of their elements when writing Java Script.

If you are writing big code it is very helpful write comments to the segment of the code as comment will not be executed, it is for code masters to check where and which segment is located. If you have the JavaScript code within your web page then in the modern browsers there are very vital functionalities from where the user can right click on the page and can see the view source to observe the use in your website. There are provisions while making the code if you do not want the visitors to watch the code then you can make it within <script> tags to employ this idea.

Variables in Java Script can be declared by using “var” statement. The switch statement takes the variable browser and compares it one by one to the values mentioned in the case statements. The break statement prevents the browser from executing the very next line of code and tells it to exit the switch block.

There is one different way you can check your conditions in Java Script- this one specifically if you want to assign a value to a variable based in a condition. Programming loops let you execute the same block of code over and over again as many times as you like. The simplest example would be printing the numbers 1 to 10 or 1 to 100. The for loop is typically used when you can predict exactly how many times a piece of code. The while loop effectively tells your browser as long as this condition is true keep executing this block of code. You would typically use a while loop to check a condition rather than execute code a specific number of times this reducing the page load times.

What will Web 3.0 have in store for us? 2

Internet is ever evolving process. With due course of time in relationship with speed of internet upload and download speed the performance of website also see a comparatively newer graphics as it does not provide immense difficulties in loading of web page and does not have too much of lagging into downloading of webpages. Web 3.0 and web 4.0 and so one does provide one of immense change over into website and performance of website in correlation of website performance.

This article is the series of article which provide immense performances issues and from it comes the https or SSL website that makes website to load into immense possibilities and remove difficulties of page loading and performance issues. When the website management and its relation with performance comes into advance the content management system as well as the performance issues such as no latency of page loading and smoother performance of page performances comes into mind.

At one time the cost of SSL does come into advance and it was costly but now with the advance of content management system such as cloudflare does come into prominent when we think about the presence of smoother performance issues and it does provide several configuration options such as dns management and performance issues and it provides one of the most intelligent performance management and it provides one of most outstanding speed up of website.

In the hosting part one can find different management such as compressing images from server side such as smush image compression and also all of HTML, Ajax, java script files runs from another server and it loads them quickly and this is what web 3.0 is known for. In this way, even if the size of website is large but it comes from different speedier hosts and servers and loads all of these with faster and optimized compression and that is what modern website is consists of.

With AutoMinify you can reduce the size of the website code and thus it loads faster and in this way we can see the modern website and web runs as it segregates each and every part of website and then performance of website that matters the most and with each and every part is running with third party server the performance management comes into prominence. Most of website runs with CSS (Cascade Style Sheets), JavaScript and HTML and all of these can be compressed from another sever and thus spreading of website to and far and then running with these website makes it the most prominent part of running the new web.

In comparison with Brotli compression, the Gzip compression is inferior. So, most of content distribution website such as cloudflare works with Gzip compression and also it has preference for Brotli compression which works nicely than inferior. Caching of website does make page load faster and when it comes from the side of server such as Varnish cache provides faster website management. It works straight from server side and can cache both static and dynamic content to make and run website in faster way.

In the web 3.0 side of development we do find that server side management of resources such as static and dynamic files comes into prominence and it does provide one of most anticipated management of website construction and in this way website runs with different versions. It aims to provide faster web access for people and thus provide one of faster internet with live cloud management as well as more and more differentiated performance management.

The evolution of web and its continuity and its constant growth and evolve through various phases and layers . Then initial phase the dot com the age of bubble then came the Web 2.0 the cloud stage , social networking and lots more user made content lurks around the web. Now we are entering into the Web 3.0 era where ours live more involved with the web than never before we have had.Web 3.0 will ultimately removes the massive digital divide among us and will make the world of web a happier and more useful places to live it on. Web is based on many layers of standards and protocols.

If you have five computer and want it to connect each other then wiring option is hailed in this case. Then after some time you want to connect yours five computers but at different cities , Easier method would be make one computer a host computer say a hub and then make the other computers spoke like name the other computers with different numbers for identity and then connect those computers with their unique identity numbers. ”This is known as protocol and the foundation of internet in the internet term is called TCP/IP. Most TCP/IP networks use subnets in order to effectively manage routed IP addresses.

The closest matching subnet is calculated for the range that you specified in From and To. The range of addresses in the closest matching subnet may exceed the range that you specified. Unless the addresses specified in From and To are subnet boundaries, the range based on the calculated subnet will be larger than the range that you specified. To avoid this, specify a range that falls on subnet boundaries. For example, if you are using the 10.0.0.0 private network ID for your intranet, a range that falls on subnet boundaries is 10.0.1.168 to 10.0.1.175. Or, if you are using the 192.168.0.0 private network ID for your intranet, a range that falls on subnet boundaries is 192.168.1.0 to 192.168.1.255. “ (Microsoft) Also Microsoft adds “Transmission Control Protocol/Internet Protocol (TCP/IP) is the most popular network protocol, and the basis for the Internet. Its routing capabilities provide maximum flexibility in an enterprise-wide network.

In Windows XP TCP/IP is automatically installed. On a TCP/IP network, you must provide IP addresses to clients. Clients may also require a naming service or a method for name resolution. This section explains IP addressing and name resolution for Network Connections on TCP/IP networks. It also describes the FTP and Telnet tools that are provided by TCP/IP. ” So the situation now is you have hundreds of computer connected to each other with unique identifiable numbers making the network which we called the internet.

First and foremost task is to identify each data generated through these connected computers with a simple tools but unfortunately this has not been done even today and for data reading we have to use a multiple of formats and this seems not a viable option. The next option is to identify the data in one common language format and display on the screen . Through this the HTML languages evolved and then the web browsers which identify these languages and make it readable for the end users. Through HTML even the users can create contents and deliver to the internet and makes his appearance through it. Still there are challenges.
