React-JS v/s Plain-Javascript

Overview

• Web apps that are complicated and dynamic have been on the rise along with technology.The creation of new frameworks, libraries, and tools has sped up the development process.
• Performance problems will arise when creating apps with a lot of interactive features and user interaction. Due to JavaScript's support for the majority of browsers, web apps and even business applications are created with it.
• As a front-end developer, you are surely aware that Plain JavaScript is the most widely used browser-based language and that ReactJs is one of the most well-known JavaScript frameworks. Without these two, current front-end development is impossible. These two technologies resembled one another in the beginning. Building user interfaces for each of them involved the same elements. React and Plain JavaScript, however, both underwent development throughout time.
• However, the question that keep touring in users’ minds are the benefits of ReactJS v/s Plain Javascript.

What is Plain Javascript?

• Using JavaScript without any additional libraries or frameworks is referred to as using "plain JavaScript." The standard, fundamental implementation of the language as specified by the ECMAScript specification is referred to as "vanilla JavaScript," or just "JavaScript."
• JavaScript is a high-level, interpreted programming language that is widely used for client-side web development. It is used to create interactive and dynamic user interfaces, handle user input and events, and make asynchronous requests to a server. JavaScript is an essential component of the modern web and is supported by all major browsers.
• JavaScript is an object-oriented language that uses syntax and concepts inspired by several other programming languages, such as C and Java. It is a loosely-typed language, which means that you don't need to declare the data type of a variable before using it.
• JavaScript is used for a wide range of tasks, including form validation, creating animations, handling user interactions, and making dynamic updates to a page without requiring a full page refresh. With the rise of Node.js, JavaScript has also become a popular choice for server-side development, making it a full-stack language that can be used to build complete web applications.
• With regard to how the UI and data specifications of an app can be changed, Javascript is a scripting language that has no limitations. The outcome is more flexible apps that are developed or authored. The optimal outcomes for an app can't be achieved in this way, though. Later, it may result in problems. It makes sense that you wouldn't want any complications while developing an app.
• You can write code in plain JavaScript that executes on a server using Node.js or right in the browser. This code is capable of handling events, manipulating the Document Object Model (DOM), making HTTP requests, and other activities that are frequently required in web development.
• Simple and complicated apps can be created with plain JavaScript, but as the application's size increases, management and maintenance might be difficult.
• You may be aware of jQuery, which is the only well used library included with Plain Javascript. jQuery is a fast, compact Javascript framework that works around JavaScript's built-in capabilities to make it simple to use and consistent across browsers. Javascript, which supports document transversal, manipulation, animation, and event handling, has it made simple.
• One great thing about jQuery is that it doesn't impose any limitations on a library like ReactJS, allowing jQuery applications to be grouped with Plain JS. One great thing about jQuery is that it doesn't impose any limitations on a library like ReactJS, allowing jQuery applications to be grouped with Plain JS.

What is React JS?

• React (ReactJS) is a Javascript library that provides guidelines for creating user-friendly programmes. It is open-source and free.?
• React carries out this wonderful work by establishing a very specific set of rules for the direction in which data can move through the app and the appearance of the user interface (UI) as a result of ongoing changes in data, such as coding.?
• To specify the flow of data across the app and other UI-related functionalities, several additional libraries set a variety of boundaries. Angular and Vue are the two most popular ones.
• ReactJS is maintained by Meta (previously Facebook), a community of web developers, and web development firms, as we learn more about it.The best thing about ReactJS is that it can be used as a foundation for developing mobile apps or single-page websites.?
• React solely cares about managing state and rendering it to the page object model (DOM). Additional libraries are needed when creating React apps for routing and specific client-side features.

Advantages of Plain Javascript

• React is a more modern technology, which has contributed to its rise in popularity. Contrarily, plain JavaScript has been around for a while and has undergone little changes. Having said that, there are several benefits to using basic JavaScript. The Advantages of Simple JavaScript.
• React is a more modern technology, which has contributed to its rise in popularity. Contrarily, plain JavaScript has been around for a while and has undergone little changes. Having said that, there are several benefits to using basic JavaScript.
• The speed of pure JavaScript is its primary advantage. Your project will run faster than it would if you utilised React since JavaScript was created with performance in mind and is supported by the majority of browsers and platforms. Plain JavaScript's second benefit is its simplicity.
• Because there are no complicated libraries or configurations to make before you start creating an application with plain JavaScript, it offers a simpler setup.
• The React framework promotes code reuse and makes it simpler for programmers to create modular code for multiple user interface components of an application. Because you won't have to bother about sorting out module dependencies or figuring out how components should interact with each other on the same page, you can focus on creating the most crucial elements of your game.
• In addition, React offers features like state management and routing, which are typically necessary for business apps. This kind of application framework makes considerable use of JavaScript and does not provide it on its own.This could be a crucial point to take into account when weighing your options against the advantages of straightforward JavaScript if you're considering building a sizable enterprise application using the React framework.

Disavantages of Plain Javascript

• We should define standard JavaScript first. A programming language called plain JavaScript is used to build client- and server-side apps.
• The absence of structure and syntax in plain JavaScript makes it difficult to use without writing a lot of code. If your programme is huge, this can take longer and result in issues in your code. Debugging can be quite frustrating if you have no expertise with programming.
• Another drawback is that basic JavaScript won't function if your programme needs a lot of structure and features.

Advantages of React JS

• React has countless advantages. As it becomes more and more popular, it must offer developers or individuals something exceptional that compels them to use it over standard Javascript. Why then wait? Let's look at some of the alluring advantages you can get from employing it.

Highly proactive

• ReactJS is quite easy to use. It adds interaction to any user interface's design. Additionally, it enables time-saving, quick, high-quality, and scalable application development.

Declarative

• ReactJS also permits significant data changes to automatically affect the chosen UI components, which is a huge advantage. You no longer need to update your user interface thanks to this fantastic functionality; everything will be done for you.

Provides reusable Components

• Developers can easily repurpose the numerous reusable components that ReactJS offers in order to build new web applications. Because it allows them to reuse the features created for other apps with the same functionality, reusability is like medicine for web developers. All of it results in a decrease in development work and perfect performance.

SEO-friendly

• We must accept that React JS was released following extensive study and development by Facebook. Because of this, it stands out from the great majority of the crowd (front-end libraries) and gives developers the tools they need to create UI that is reliable and SEO-friendly across all major browsers and search engines.

Successful Data Binding

• One-way data binding is how ReactJS functions. It enhances clarity and lessens confusion. Anyone can keep track of every change made to a segement of data.

Disadvantages of React JS

• For people who are brand-new to JavaScript development, React is not the greatest choice. React might not be the ideal choice if you are a developer with a solid grasp of JavaScript and its structures. Additionally, React has a challenging learning curve that new users may find overwhelming.
• React includes a tonne of boilerplate code that is not required for the majority of apps.
• The fact that React does not support IE11 or earlier versions is another drawback. If your application is only compatible with IE11 or earlier browsers, this could be a problem.
• Finally, if you wish to use React on other platforms, such as mobile apps and websites, there are disadvantages to this approach. Although React is supported on these platforms, because React Native and Progressive Web Apps (PWA) are wholly distinct technologies in their own right, you cannot use the same code or capabilities from the web app with either of those platforms.

Comparison

• React could be a suitable alternative for you if you're searching for a simple to develop, interactive, and user-friendly app. One of the numerous advantages of React is the ability to group components and use them as a single entity. Less code can be used to create apps that are more sophisticated.
• Another advantage of React is the simplicity with which reusable components can be created, each of which may be utilised independently in multiple websites or apps.
• However, you might find that plain JavaScript works well for you if your project doesn't have the sophistication of a web application. While plain JavaScript may not have all of the functionality of React, it is simpler to understand and has a more straightforward syntax.
• The key advantage of utilising plain JavaScript is that it can be used with any code editor or IDE without the need to install any additional software, in contrast to React, which can only be used with macOS operating systems.
• Additionally, employing plain JavaScript could provide you with the simplicity you require if your app doesn't require the ability to reuse components across several apps or websites.

Differences

• A JavaScript library called React aids in the creation of user interfaces. The functional programming paradigm is applied. Writing the markup for your app and rendering it into a virtual DOM are the initial steps in creating a React application. The rendering mechanism utilised by React is then built on top of this virtual DOM.
• Contrarily, plain JavaScript doesn't require any unique libraries or tools. All you have to do is tell the browser what you want, and it will render it. JavaScript can be used directly without the usage of any libraries or tools.
• However, it will be challenging to implement some of React's functionality, such as handling state changes or using event listeners, in plain JavaScript because you need to use proxies to make them function properly.

Pros and Cons

• React is a JavaScript package that creates reusable, composable, and effective components, allowing developers to create complex user interfaces. However, Internet Explorer 9 and earlier do not support React. React has the additional drawback of taking longer to set up than standard JavaScript.
• On the other hand, simple JavaScript can be utilised to create interactive apps without the need for a complex setup. You don't have to worry about the challenges of learning a new tool or library because simple JavaScript may be used without libraries. When using a browser that does not support React, you can also use simple JavaScript.

When to Choose one Over Other?

• A JavaScript library called React enables programmers to design single-page apps. React provides a component-based approach to app development, which greatly increases code reuse.
• The ability to create web pages similarly to how you would in any web browser is provided by the plain JavaScript library, which is more suited for small applications. Since plain JavaScript lacks structure and reusability, it is not suitable for use in large-scale applications. Component-based development and great performance are only a couple of the advantages that React offers.
• However, because to its simplicity and versatility, Plain JavaScript may be a better option than the React framework if your programme needs a lot of code.
• You should use basic JavaScript for simple applications. For instance, pure JavaScript should be used for a straightforward app that only needs to execute in the browser. The rationale for this is that well-structured, modular code makes performance changes and maintenance much simpler. A smaller learning curve is also a benefit of its simplicity.
• It won't, however, offer the same level of user interactions and interactive components required for programmes like gaming or business applications.

Conclusion

• Though both are at their finest in their respective iterations, ReactJS has a greater chance of dominating the developing world due to its incredible capabilities and advantages. You may create a scalable web application with ReactJS that will help you grow your company.?
• As a result, you have a new perspective on the revenue and conversions of your company. Even though the huge community of developers considers Plain Javascript to be one of the most popular programming languages, it doesn't produce scalable outcomes.
