ReactJS Training in Pune

The future of ReactJS

• Facebook and the entire ReactJS team have demonstrated the commitment to enhancing ReactJS efficiency.
• This is crucial to weather the fast emerging competition from other frameworks such as Vue.js. Some of the things to expect in future releases include;
• ReactJS enthusiasts should expect new render types.
• For example, the ReactJS team is likely to add unique fragment syntax to the JSX that does not need keys.
• Developers are also expecting improvement in error handling.
• In the past, cases of runtime errors during rendering often put ReactJS in an awkward broken state.
• This requires regular page refreshing.
• The current model of addressing the error is throwing it inside the component or lifecycle methods.
• Though this helps to prevent rendering corrupted data, it is not the best idea for better UX.
• Enhancing server-side rendering.
• Though the latest ReactJS comes with an entirely rewritten server render which makes it very fast and ideal for streaming, it is a great place to pitch improvements.

Why ReactJS is great for businesses

• In the tech-driven arena, entrepreneurs and developers are always looking for better methods of giving their businesses a competitive advantage..
• One great technology for helping enterprises to outdo their competitors when creating web apps is ReactJS.
• ReactJS allows enterprises to craft apps with better UI to enhance user experiences.
• This is the technology they need for better user engagement, higher click-through-rates, and conversions.
• Businesses that use ReactJS are assured of better performance compared to those that use other frameworks.
• Because ReactJS helps to prevent updating of DOM, it means that the apps will be faster and deliver better UX.
• ReactJS was designed to help improve the total rendered pages from the website server.
• Besides, it utilizes nodes to render on the client-side. Having the capability to modify built tooling and even scale back on maintenance budgets makes ReactJS highly efficient.

Why Use React JS?

Simplicity

• The first thing that gets so many people to use ReactJS in their projects is probably its simplicity.
• React is a JavaScript library so if a developer is familiar with JS functions, they will have an easier start with ReactJS.
• With this library, developers define interfaces with an HTML-like syntax called JSX.
• As a result, HTML and CSS code is produced. React’s API is very small, yet powerful, and all
• you need to do before you start is to learn a few basic functions.
• A little bit of a learning curve appears when you want to use React with other JS libraries, such as Redux, Material UI or Enzyme.
• While not a part of the React stack, such libraries add additional capabilities and allow you to manage React components more easily.
• The most common libraries are well documented and should cause no trouble to any developer.
  Simplicity of React comes with certain benefits for businesses.
• Those already relying on other JavaScript frameworks will have an easier transition to React.
• Even if your goal is to just try the library, without committing to a full-fledged transition, this also won’t be difficult.
• And if you need to scale in the future or change the development team, the abundance of ReactJS developers on the market will make things a lot easier.

Developers 

• The research performed by StateofJS.com shows that JavaScript developers are really happy about using React in their projects, comparing it favorably to its closest competitors such as Angular.
• What's more, at the time of writing, nearly two-thirds of thousands asked said that they used ReactJS and would use it again.
• This should have gigantic meaning for anyone planning to run any software product for the next few years.
• If developers are so excited about React, this means there will be more and more of them out there.
• This, as a result, means that there will be big ecosystem of various React libraries and tools to enhance the development.
• As a result, ReactJS will become more powerful with each one added.
• There will also be a lot of talent on the market, ready to build new projects and support existing ones. ReactJS is here to stay.

Reusable elements

• This is where the real beauty of React comes from.
• If you’ve ever used some design tools like Sketch, you must know how easy and intuitive building interface elements is.
• You draw a rectangle and resize it to your liking. You then insert some copy inside and group them together as a ‘text field’.
• Then, you duplicate the group several times, draw an attention-grabbing button with copy and wrap it all up with a frame and a header.
• You then group it all as a ‘contact form’. Whatever business this project is for, you’ll likely reuse this contact form multiple times throughout the project.
• It absolutely doesn’t make sense to design the form from scratch every time you need one so obviously a decent designer will just insert already grouped elements with just a few clicks.
• Development used to be much more complex than that but ReactJS gives us the tools to do exactly the same thing.
• Each React project is built using the so-called reusable components.
• This means that each element of the interface that you’ve already built, can be used anywhere in your project by just calling from other components. You write such a function once and can reuse it anywhere.
• What’s more, you can group these elements into sections or pages and insert them anywhere around the project with the same functions.
  Reusable elements in ReactJS also follow a simple mental model.
• If a component is given the same data multiple times, it will always yield the very same set of HTML and CSS. Such capability, called idempotence, makes it easy to reason about and to test.

Development of React JS

• All of the buttons in your application must be styled in the same way.
• In ReactJS, you can define a component and reuse it anywhere instead of copy-pasting the same code over and over again.

Important benefit

• Its presentation is separated from its semantics.
• Designers are free to build a component library without worrying about business logic and engineers can construct interfaces from the components, knowing they’ll look good without any effort.
• All of these come with a lot of advantages for any business.
• Thanks to reusable components, your platform is consistent and, as a result, easy to navigate for users.
• There’s less code to be written without losing any functionalities and this inevitably leads to faster development.
• It’s also simpler to add new features and test them as you have tons of code already written and ready to be reused.
