" JAVA-SCRIPT "

• INTRODUCTION : 

         Coding depends on two types of languages; content-markup and programing. In coding programing languages are the important one. At present, there are a lot of programming languages have been used; JavaScript is the most popular and suitable programing language. It is also the programing language of the web and very easy to learn. 

• JAVASCRIPT-DEFINATION : 

            JavaScript is a dynamic computer programming language. It is lightweight and most commonly used as a part of web pages, whose implementations allow client-side scripts to interact with the user and make dynamic pages. It is an interpreted programming language with object-oriented capabilities.

• JAVASCRIPTS-FUNDAMENTALS : 

            JavaScript is a programming language that allows you to implement complex features on a website, such as dynamic elements or interactivity. JavaScript is executed once the information from the HTML and CSS in the source code has been parsed and constructed. This coding language is very easy to learn. Even a person who knows almost nothing about JavaScript can also learn it easily from the following video which was created by 'Mosh Hamedini".

It has also some important elements to perform; such as array, functions, loops, operators, objects etc, which can be also learned through the video.

• HOW TO OPERATE :  

             JavaScript is what is called a Client-side Scripting Language. That means that it is a computer programming language that runs inside an Internet browser (a browser is also known as a Web client because it connects to a Web server to download pages).

The way JavaScript works is interesting. Inside a normal Web page, you place some JavaScript code (See how web pages work for details on Web pages). When the browser loads the page, the browser has a built-in interpreter that reads the JavaScript code it finds on the page and runs it. To run JavaScript you need a platform to perform or code in it. Some of them are- HS8, VS-studio etc.

Here's a video for operating JavaScript at visual-studio by "Tech decode tutorials".

In JavaScript language ; operating and debugging is definitely very important; that's why VS-studio is one of the great option.  

• USE OF JAVASCRIPT : 

           JavaScript is commonly used for creating web pages. It allows us to add dynamic behavior to the webpage and add special effects to the webpage. On websites, it is mainly used for validation purposes. JavaScript helps us to execute complex actions and also enables the interaction of websites with visitors.

At present there are a lot of use of JavaScript have been going on. Some of them are-

1. Web Applications;  As day-by-day there is a continuous improvement in the browsers, JavaScript gained popularity for    making robust web applications. We can understand it by taking the example of Google Maps. In Maps user is just required to click and drag the mouse; the details are visible just by a click. There is a use of JavaScript behind these concepts. 
2. Web-development; 

   JavaScript is commonly used for creating web pages. It allows us to add dynamic behavior to the webpage and add special effects to the webpage. On websites, it is mainly used for validation purposes. JavaScript helps us to execute complex actions and also enables the interaction of websites with visitors. Using JavaScript, it is also possible to load the content in a document without reloading the webpage.

3. Mobile Applications; Now a day's mobile devices are broadly used for accessing the internet. Using JavaScript, we can also build an application for non-web contexts. The features and uses of JavaScript make it a powerful tool for creating mobile applications. React Native is the widely used JavaScript framework for creating mobile applications. Using React Native, we can build mobile applications for different operating systems. We do not require writing different codes for the iOS and Android operating systems. We only need to write it once and run it on different platforms. 
   
   
   
4. Games; JavaScript is also used for creating games. It has various libraries and frameworks for creating a game. The game can either be 2D or 3D. Some JavaScript game engines such as Physics JS, Pixi.js help us to create a web game. We can also use the WebGL (web graphics library), which is the JavaScript API to render 2D and 3D images on browsers.
5. Presentations; JavaScript also helps us to create presentations as a website. The libraries, such as reveals, and BespokeJs, can be used to create a web-based slide deck. They are easier to use, so we can easily make something amazing in a short time. The Reveal.js is used to create interactive and beautiful slide decks with the help of HTML. These presentations work great with mobile devices and tablets. It also supports all of the CSS color formats. The BespokeJS includes animated bullet lists, responsive scaling, and a wide variety of features.

6. Web server; A web server can be created by using Node.js. Node.js is event-driven and does not wait for the response of the previous call. The servers created using Node.js are fast and don't use buffering and transfer chunks of data. The HTTP module can be used to create the server by using the create Server()method. This method executes when someone tries to access port 8080. As a response, the HTTP server should display HTML and should be included in the HTTP header. 

• BENEFITS : 

            Here are some benefits or advantages that we can take from JavaScript. Those are-

1. Less server interaction
2. Immediate feedback to the visitors
3. Increase interactivity
4. Richer interfaces
5. Controlling frame navigation
6. Include a plug-in or a java applet inside a page
7. Images can swap when the user moves mouse over them
8. Calculating at the websites 
9. Apart from all the advantages, JavaScript is very easy to learn.

Video-3: 5 reason to learn Javascript

From this video you will be able to learn 5 most important reason to learn JavaScript. At present there are a lot of online platform for learning JavaScript and many more language is here. The most familiar two of them are-

*W3-SCHOOL

&

*CODE ACADEMY

• CONCLUSION :

             JavaScript is a wonderful technology to use on the web. It is not that hard to learn and it is very versatile. It plays nicely with other web technologies — such as HTML and CSS — and can even interact with plugins such as Flash.

It is called the programming language of the web. Hence, there is no need for cross-checking the fact that JS is among the best programming languages to start learning in 2019. JavaScript is the main powerhouse behind the rapidly evolving Internet. It is the present and will be the future.

So that's all about JavaScript ended up here.
