The Script of the Java Script

Hello, this is MD MOQADDAS an automation engineer that always integrate tools each other sometime they integrate DevOps tools with Machine Learning, Deep Learning, Cloud Computing, Web Techonologies, Mobile App and with lots more tool

In this article, I am going to give a special brief and some interesting facts about javascript let’s start the journey

Summary -:)

1. What is Front-End
2. How to create Font-End
3. What is Java Script
4. How to write code in JavaScript for front end
5. Reasons to use JavaScript in web development
6. Why JavaScript important in web development
7. Features of Java Script
8. Examples of scripted behavior
9. How Uber handle loads of data

Before going ahead let’s keep some point in minds so that understanding the thing will be very easy

We as a technical guy we know if we want to instruct the machine in this case we have to take the help of programming languages it may be Java Script, Python, C, C++, Java, C#, Rubbi, Dart, Kotlin, PHP and lots more I am only referring some common programming language because each language has own specification and each one also very great in own field.

By using these programming languages we do lots of things and helps the world but finally, at least we need something to represent these services and facility to the common man who doesn’t know about the programming language, so here we human being created some page to present to the common and we write all the instruction to the developer side

I want to point out here which we present to the common man in the form of page known as Front End or some time User Interface, these FrontEnd and User Interfaces go behind the scene somewhere and do something known as BackEnd.

Here I am going to talk about the Frond-End and a little intro about the backend.

What is Frond-End -:)

In very simple which we see from our side on the machine known as Frond-End, in the computer world when we see on the website, desktop, and mobile known as frond-end.

But the point here is how to create frond-end we know that we see on the website and other platform but how to create it.

How to create Font-End -:)

There are three languages every web developer speaks HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript.

why web developer speaks the HTML, CSS, and JavaScript

HTML -: This only responsible to present the content on the web or Front-End

CSS -: It only responsible to design or style the HTML content

Java Script -: It is responsible to show the HTML element dynamically and do some greater design and animation by integrating with CSS.

This article totally about the Java Script so let’s discuss it

What is Java Script -:)

Java Script is a programming language that mostly used in the front end but we can also use it in the backend.

How to write code in JavaScript for front end -:)

Before going ahead first we have to understand how to create HTML code, so we create HTML code by following the method

→The file extension should be “html” or “htm”

save as file

Click on it

see the HTML content

Now let's use HTML and javascript code

Output -:

Now discuss the code content.

We can write HTML code anywhere but for writing java script we have to put only inside <script></script> tag

Reasons to use JavaScript in web development -:)

1. Adding interactive behavior to web pages. JavaScript allows users to interact with web pages
2. Creating web and mobile apps
3. Building web servers and developing server applications, Game development

Why JavaScript important in web development -:)

1. JavaScript is a programming language used primarily by Web browsers to create a dynamic and interactive experience for the user.
2. Most of the functions and applications that make the Internet indispensable to modern life are coded in some form of JavaScript.
3. JavaScript is the programming language of the internet
4. Big Community Support

Features of Java Script -:)

1. It’s one of the few languages that isn’t run on the server that hosts the web page
2. JavaScript animations use the viewer’s device processor to run themselves
3. It’s easy to learn
4. A developer can write a DOM for a web page using JavaScript.
5. Compiler-free programming language

Examples of scripted behavior -:)

1. Loading new web page content without reloading the page, via Ajax or a WebSocket
2. Web page animations, such as fading objects in and out, resizing, and moving them.
3. Playing browser games.
4. Controlling the playback of streaming media.
5. Generating pop-ups.
6. Validating input values of a web form before the data is sent to a web server.

How Uber handle loads of data -:)

Uber, is an American technology company. Its services include ride-hailing, food delivery, package delivery, couriers, freight transportation, and, through a partnership with Lime, electric bicycle and motorized scooter rental.

We know that by using java script without loading the page do lots more thing so uber also this concept as

Uber needs to handle loads of data in real time. They have millions of requests coming in continuously, and that’s not just hits on a page. Uber needs to track driver locations, rider locations, and incoming ride requests. It has to seamlessly sort that data and match riders as fast as possible.

Without Java Scirpt none of the industry works now a days, all company used java script in own custom way, like

→ Google use java script by create own customer java script called “Angualr Js”

→ Facebook use own custom java script

Like this each industry use it
