React JS is highly sought after for its versatility and ability to simplify the building of apps and websites alongside creating UI test cases and reusing existing website code to improve overall UI and web application performance.
To find a perfect fit for your team, you need to establish who that would be. To give you some examples: a good teammate, excellent level of English, business knowledge, with 3 years of experience, growth-attitude, etc.
To filter the best possible hires, you need a set of steps. We call it a hiring funnel (it’s a lot like a sales funnel). Establish how you want to check your candidate’s skills, way of thinking, culture, and team fit. Prepare questions in advance and take a team member to the interview.
Hiring React JS developers seems difficult because there are a lot of them in the market (but not everyone as experienced and promising as you wish), and there is also high demand. A well-thought-out process is your key to overcome these obstacles.
React JS is so popular, quite a few major business enterprises are well-acquainted with the software. Companies that use React JS include the following:
1. Easy to Learn and Use
2. Creating Dynamic Web Applications Becomes Easier
3. Reusable Components
A ReactJS web application is made up of multiple components, and each component has its own logic and controls. These components are responsible for outputting a small, reusable piece of HTML code which can be reused wherever you need them. The reusable code helps to make your apps easier to develop and maintain. These Components can be nested with other components to allow complex applications to be built of simple building blocks. ReactJS uses virtual DOM based mechanism to fill data in HTML DOM. The virtual DOM works fast as it only changes individual DOM elements instead of reloading complete DOM every time.
4. Performance Enhancement
ReactJS improves performance due to virtual DOM. The DOM is a cross-platform and programming API which deals with HTML, XML or XHTML. Most of the developers faced the problem when the DOM was updated, which slowed down the performance of the application. ReactJS solved this problem by introducing virtual DOM. The React Virtual DOM exists entirely in memory and is a representation of the web browser's DOM. Due to this, when we write a React component, we did not write directly to the DOM. Instead, we are writing virtual components that react will turn into the DOM, leading to smoother and faster performance.
5. The Support of Handy Tools
React JS has also gained popularity due to the presence of a handy set of tools. These tools make the task of the developers understandable and easier. The React Developer Tools have been designed as Chrome and Firefox dev extension and allow you to inspect the React component hierarchies in the virtual DOM. It also allows you to select particular components and examine and edit their current props and state.
6. Known to be SEO Friendly
8. Scope for Testing the Codes
ReactJS applications are extremely easy to test. It offers a scope where the developer can test and debug their codes with the help of native tools.
1. The high pace of development
The high pace of development has an advantage and disadvantage both. In case of disadvantage, since the environment continually changes so fast, some of the developers not feeling comfortable to relearn the new ways of doing things regularly. It may be hard for them to adopt all these changes with all the continuous updates. They need to be always updated with their skills and learn new ways of doing things.
2. Poor Documentation
It is another cons which are common for constantly updating technologies. React technologies updating and accelerating so fast that there is no time to make proper documentation. To overcome this, developers write instructions on their own with the evolving of new releases and tools in their current projects.
3. View Part
ReactJS Covers only the UI Layers of the app and nothing else. So you still need to choose some other technologies to get a complete tooling set for development in the project.
4. JSX as a barrier
Clocked at 3k gzipped, Preact can be an excellent choice to build websites if performance is not the most profound concern for you. It is one of the smallest alternatives to React JS out there.It supports most of the modern-day browsers and IE9+. However, if you’re looking forward to a library that supports Facebook synthetic events system, then this is not the right choice.Preact offers several other features nifty features such as the rendering of both props and states, linked state, and the utilisation of ‘class’ instead of className.
The sole reason to create this library was to introduce the lighter version of React JS. Unlike Inferno and Preact, there is no compatibility package require. One can use it directly via webpack alias.Its compatibility level with other React components is much greater than the other two frameworks mentioned above. However, it is neither the fastest nor the smallest among all libraries.Neither does it supports server-side rendering, nor does it supports client-side hydration. Despite using React DOM servers for those functions, developers haven’t seen any seamless transitions.
Backbone JS can be considered as the right alternative to React JS as it offers a structure to JS heavy applications by providing models with value-binding and custom events, collections with a rich API of various functions, views with declarative event handling, and connects all of them with your existing apps over a RESTful JSON interface.
Aurelia is written using ES2016. Without any external dependencies except polyfills, it seamlessly integrates with web components.Aurelia is made of smaller and more focused environments rather than following the monolithic framework approach. You can create applications using all or selected modules.It also offers two-way data binding to any object. Its extensible HTML compiler allows you to create custom HTML elements, control template generation, and attach new behaviours to the existing HTML elements.
It holds a strong position in top alternatives to React JS. Ember’s handlebars integrated templates allow you to do more by writing less code. This template updates automatically when the underlying data changes.It is designed to increase the productivity of a developer. It is API-friendly and helps one to enhance the development speed since it incorporates all the common idioms.
Riot JS allows us to create user interfaces with custom tags using simple and intriguing syntax. It also has a virtual DOM which is similar yet faster than React.If you’re looking for a small-sized UI library, then Riot is the right choice for you. It’s custom tags let you build complex views using HTML. Moreover, it does not require any extra HTML root elements, fancy custom attributes, or data attributes.
Mithril is a modern-day client-side JS framework for developing Single Page Applications. It is fast, small (less than 10kb gzip), and offers routing and XHR utility out-of-the-box.
