JavaScript is an object oriented language. Javascript for Web Development its Important thing. The biggest advantage of the current era is that it can be converted from small to large programs. Also, JavaScript is essentially an interpreted language that requires no compilation of its preceding commands.
And the biggest advantage of JavaScript is that you can execute the script in the browser that you use. In a word, JavaScript is a simpler and shorter form of programming language.
What is Javascript?
One of the most popular and widely used client site or browser base scripting languages supported by all browsers is JavaScript.Netscape developer "Brendan Aich" created this programming language in 1995 and released it to the public as Live Script in early 1996 with the Netscape 2 browser.
Again, in the same year, the name of December 4 was changed to JavaScript (JavaScript). which is abbreviated as (JS).
Do you want to build automated web applications? Then of course it is important to know your java script. And it is impossible to build automated web applications without JavaScript. If you know the program, it is not that complicated to work.
JAVA and Javascript are completely different languages. JAVA is a complete object oriented programming language and Javascript is a scripting language. JavaScript is a programming language but it works only in the browser whereas with JAVA a completely separate application can be made which runs on the PC.
What kind of work can be done with the help of JavaScript?
Any type of design can be created on the website.
Timely greetings can be given (good morning, good night).
Live activity animations can be created with the touch of a mouse or smartphone.
Providing QR code, complex information, location etc.
Browser name, IP, ISP all information can be reported to the user.
While accessing various web pages, you can be given the opportunity to follow and accept the set policies.
Automatic dynamic dropdown menus and automatic popup windows can be created.
The more you learn about JavaScript, the more ideas you'll get when you need JavaScript to do more.
JavaScript is basically made up of 3 things:
1. ECMAScript (it is the core functionality of JavaScript).
2. DOM (Document Object Model - works with the content of web pages).
3. BOM (Browser Object Model - works with the browser).
Why javascript is important or why javascript is needed?
JavaScript is the driving force behind programming for highly dynamic engagement with traffic. With HTML and CSS you can only build the basics, but you can't have interactive or precise controls. To be interactive, you must rely on an object oriented language. And in that case the most important and useful is this javascript. The importance of JavaScript to make it interactive, executable, dynamic is unmatched.
Three of the most used and popular technologies on the web are:
1. HTML
2. CSS
3. JavaScript
All websites and web applications will have these three. It means that they are the main power of the web.
JavaScript has a huge collection of libraries and frameworks that can be used to do all kinds of things. There are two main ways JavaScript is used on the web:
1. Client Side: Runs in the browser only
2. Server Side: Runs on the server, usually code generated by the server itself (eg, Node.JS)
JavaScript is a very lightweight, cross-platform and object-oriented programming language.
Lightweight: JavaScript doesn't put too much load on the machine, and many techniques make it execute faster than other languages.
CrossPlatform: You only need to build the application once. For this you don't need to think about which operating system, Mac or Windows or Linux or anything else your application will run on. Just as we can access all websites from all operating systems, JavaScript applications will also run on all operating systems without much need to be developed separately for each operating system.
Object Oriented: Almost everything in JavaScript is an object. You are an object, you have a nose, ears, name, skin color. They are all properties of your mean object.
1. Simplify: The framework simplifies tasks that you may take years to complete. In that case you don't need to do much behind the scenes work. Many things are available ready-made. The advantage is that you can work on your main idea without doing the basic work. It means that you can spend time on more complex ideas and you can make better level applications.
2. Safe: Since the developer community is huge, almost all bugs are caught and fixed. So popular frameworks are very safe. Developer community compared to other languages
3. Open Source: The best thing is that most of the frameworks are completely open source so you don't have to pay extra or your application is completely yours.
Libraries and Frameworks.
Libraries are generally used for a specific task or operation. It is a collection of code created by someone else with nothing to do. It is used according to its type of work. For example – by calling the animation library we can only do the animation work.
Frameworks act as the skeleton or basic structure for building an application. There are some built-in functions and codes. There is also a system to create functions according to your needs. As the entire control-flow is laid out, the developer has to complete the design by following the basic structure according to his work.
By using libraries, we can easily use custom made code in our work. No need to create new code for the same task. And with frameworks we get a structure for our designs that is easy to maintain. It's also easy to bring new upgrades into the works. Even so, the structure follows some general rules like other web pages.
The JavaScript language, equipped with a large number of libraries and frameworks, is used on nearly 90 percent of websites. Various libraries and frameworks of JavaScript are used for client side scripts, server side code, building various complex web applications, controlling dynamic and responsive tasks, etc.
The common structure of various frameworks makes them popular for a variety of tasks. Eg – Angular JS for client side work and Node JS for server side work etc. Also applications can be easily designed by calling various libraries.
Some popular JavaScript libraries:
1. Node JS: JavaScript's most popular runtime environment and the most widely used. It is usually used on the server side.Node.js is a cross-platform, open source, server layer runtime environment based on the JavaScript programming language, with data I/O in an asynchronous, event-driven architecture, and based on the V8 Node.js engine.
2. ReactJS: Maintained by Facebook. Main work is front end development. Component beige. Light, hassle-free, ultra first performance. It is based on few functions so it can be learned quickly.
3.Vue.JS: Vu JS is also in pretty good shape. Mainly used in front end development. Easy to start. And in the last few years rapidly using Vu. Although state management is a bit complex in Angular and React, it is much simpler in Vue.js.
4. AngularJS: Maintained by Google. There are two versions. Named Angular 1 and Angular 2. Mainly used in front end and development.
5.MeteorJS: Using Meteor can work on client side as well as server side. You don't need to use any other language (PHP/Ruby/Python) for this. Same functionality and performance can be worked on the server side with JavaScript.
6. EmberJs: It is also basically used to create one page applications.
7. ReactNative: Want to build a mobile app using JavaScript and React? Yes, then React Native is for you. You can create complete mobile apps with React Native
8. Webpack: Usually uses multiple technologies in one application. Mostly used to bundle all together into one file and serve. Your application can have many script files. Webpack combines everything into one script and is very flexible to use.
9. ExpressJS: Specially used with Node. For creating servers and routing your applications. Very easy to learn and very useful.
10. jQuery : jQuery is a fast and feature-rich JavaScript library. It is used to modify or manipulate HTML documents, control various types of events, create animations, etc.
11. Redux: Redux is an open source JavaScript library used for controlling application state. It is commonly used as a helper with React or Angular JS for creating user interfaces. Applications built with it exhibit static behavior, are easily debugged, and have flexibility of use.
12. video.js: It is a web video player targeting HTML5. This library can be used to play HTML5 videos, use modern streaming formats, use YouTube, Flash through plugins, etc. The ability to play anything and the use of plugins make this library popular.
13. Next.js: It is an open source React front end development framework, with which various server side tasks are performed. It can be used to create static websites. It is basically a React based framework which helps in creating server side user interface.
Javascript for Web Development, JavaScript is a very reliable medium for front-end and back-end development. Everything from site design to logical design/framework is controlled using JavaScript libraries and frameworks. This ensures the safety and stability of the site as well as its external beauty and diversity. Many organizations are also working on developing these frameworks and libraries. This will make the use of JavaScript more flexible later on.
Conclusion: Javascript for Web Development, Among the numerous libraries and frameworks in JavaScript, some of the most popular libraries and frameworks are described here. Using these libraries and frameworks will make your website attractive and diverse.
