Building websites and web apps are in very demand in today’s market. Beginners can easily learn these skills and can work to make a successful career as a coding specialist.

Having a good hand in HTML and CSS can help you in the journey. Also, skills like JavaScript can also be mastered to provide you with an upper hand over others. Having the right knowledge with proper guidance can be very helpful as it will provide you with an initial boost to excel in your field.

New coding skills pop up every day in coding industries. Coders are required to update their skills, in order to satisfy the demands expected from them. If you want to be a good coder you should at least have the knowledge of the new popular skills that are growing rapidly in the coding industry. 

What are the need and use for HTML? 

HTML is also known as HyperText Markup Language. It uses a markup language to design web pages.  HTML is the merger of Hypertext and Markup language. Hypertext is used to establish the link between the web pages. The structure of the web pages is defined with the help of the markup language. A machine can understand and manipulate the text with the help of this language. These markup languages manipulate the text, images, and other content by defining specific tags.

What are the need and use for CSS?

CSS is an acronym for Cascading Style Sheets. CSS language is used to make web pages presentable. Simple language is used to apply various styles on web pages. HTML codes for the webpage don't get affected while using CSS language.

Beginners can easily understand the concepts of CSS language and can use it to control the presentation of an HTML document.

Benefits of Learning CSS

The written CSS sheets can be reused in multiple HTML pages hence saving time. Global changes can simply be made by changing the style, which automatically updates the elements in all the web pages. These clean coding techniques are useful as search engines can easily read the contents. CSS has a wide array of attributes as compared to HTML. Which enables CSS to produce better-looking HTML pages as compared to HTML attributes. Offline websites can be viewed as CSS language that uses offline catchy to store web applications locally. 

What is a JavaScript Library?

Java Script has been evolving since it was developed. It is a fast-growing language. The JavaScript language is a very well-known language and has grown in popularity in these years. It has established a system of libraries, frameworks, tools, and package managers. Many new languages can be compiled down to JavaScript. The de facto package manager for JavaScript has the largest registry in the world. If you want to be a good JavaScript developer, you have to be updated with the latest JavaScript tools and Libraries.  

The programming language, JavaScript can be used to create dynamic elements on the website or web app. JavaScript is supported by all modern browsers. Features such as validation links, advanced animation, pop-ups, etc are coded using JavaScript language for any website. JavaScript also supports client-side scripting, which can be used to build web pages and apps.

There are various codes that are used in many applications.  instead of writing these codes, again and again, pre-written JavaScript codes known as JavaScript libraries are structured.  These pre-written codes help in the easier and faster development of apps and web pages. Specific programming tasks can be accomplished using readymade components and patterns. It contains ready components, functions, and patterns, which can be used to accomplish specific programming tasks. Applications can be made more secure and efficient using these features. JavaScript framework libraries are open source and free, which makes the cost of app development significantly less.

What are Libraries?

A library is a collection of functions, objects, and classes that can be reused for different projects, hence increasing the functionality of the application. The library takes care of the implementation details by extracting the different layers. The library can be used to execute input parameters and doesn't have any structural constraints on them.

What is React JS?

React JS is a front-end framework, developed by Facebook. React JS is declarative in nature and efficient to operate. React JS allows us to build user interfaces particularly for single-page applications. React JS is a flexible library that is used to build reusable UI components for applications. It is an open-source JavaScript library. The JavaScript library is used to handle the view layer for web and mobile apps. React also allows us to create reusable UI components that can be built using React JS. Express JS can be used as a backend framework with React JS. Express JS can opt as a backend framework for Node.js, it also works as a library for many other Node JS web frameworks. Jordan Walke, a software engineer working for Facebook developed React JS. Single-page social media applications such as WhatsApp & Instagram make use of React JS.

What is JSX?

JSX is a syntax extension to JavaScript. When used with React JS, JSX is used to explain the structuring of UI and create templates. It may resemble a template language, but the full power of JavaScript backs up JSX.  developers can easily identify the errors as warning messages are displayed.

React Native

React Native is used by developers to create front-end for mobile applications. Android and IOS app developers can select from the rich library of ready components. After having a basic understanding and learning to execute solutions in React JS, React Native can be easily used to create native mobile apps. It is a JavaScript framework, using JavaScript to develop mobile applications. Unlike React JS, it uses native components as building blocks.

Props

Props, a special keyword in React, are used to pass data from one component to another. As React makes use of UI by breaking them into little reusable pieces, these components of component-based libraries need to communicate with each other, props act as the means of communication between components. As the flow of data, while using props is unidirectional, meaning the data can only flow in one direction for example only in the direction from parent to child, this makes the data transferred by props read-only. The data being passed by props from parent to child can be changed by child components.

Hooks

Render Props and High Order components are used to attach reusable behavior to a component. But they are hot to manage as a developer has to restructure all the components when you use them. React needs a better way to share stateful logic as the main components of react application in react dev tools are surrounded by layers of providers, consumers, higher-order components, render props, and other abstractions. 

Stateful logic can be extracted and be tested independently. These logics can be re-used with the help of Hooks, without changing the respective component hierarchy. 

The Popularity of React JS

Individuals can create and develop Start-up ideas with the help of React JS, as it is a very popular and highly demanded language in today's coding industry. Many well-established companies use React JS for various projects. Apps such as Facebook, Instagram, Netflix, New York Times Dropbox, Yahoo! Mail, etc are all developed using React JS as their base foundation.

The Reason to learn React JS

Developers are often confused as the presence of many open-source libraries and frameworks results in a dilemma. There are various factors that make React JS, one of the best available front-end development languages in the market. 

Front-end developers should be well aware of the JavaScript library React JS, as there are many benefits that can be used by the developers. React JS is a UI library, which makes it the best choice for the developers involved in creating UI. 

Beginners can easily learn React JS as the learning curve required by the library is quite low. React is a front-end framework with low entry demands, and the learning curve required to understand the library is quite low, which makes it friendly for beginners. Having a background in languages such as HTML, CSS and JavaScript can help you learn React JS and create UI for single-page applications. React JS has a strong community and a lot of resources making it easy for beginners. Frontend developers who can code in React JS are in very high demand in the market, making React JS one of the best paying languages available. React JS interview questions can also be prepared with the help of this course. React JS as a skill in your resume can really boost the chances of you getting that job.

Great learning does an excellent job to provide a strong foundation for beginners by providing free tutorials of React JS in Hindi, consisting of detailed and well-planned video lectures designed to target the important topics.
