Definitions of ReactJS
Table of Contents
ReactJS is a JavaScript library for building user interfaces. It is mainly used to develop UI components, such as forms, dialog boxes, and drop-downs, as well as larger applications like single page apps. React encourages reusable software components based on JavaScript.
Virtual DOM is an in-memory data structure that represents the User Interface in React, which improves performance by reducing the time it takes to render the UI.
Components are the building blocks to create React applications. They are written in JavaScript and can be composed and nested to form complex components that serve as the foundation for an application.
JSX stands for JavaScript XML, which is an extension to JavaScript that allows developers to write both HTML and JavaScript code within the same file. It helps developers to create UIs with the same syntax used for creating web components.
State refers to any data that is managed by a React application. React components use “state” to store data that affects how components are rendered and behave, and components can receive data as props from parent components.
Props are properties passed from a parent component to a child component. Props are used to manage the data flow between components in React.
Events are features provided by the React library that help developers to respond to user interactions and trigger changes to a React component’s state.
Functional Components are React components that are written as a function instead of a class. These components can be passed data and return a React element, which is a component rendered on the page.
Class Components are components written as classes that extend the base class Component provided by the React library. This allows developers to use React features like state and lifecycle methods to create components.
ReactJS is a powerful library for building user interfaces that opens up a world of options for developers. Understanding its key definitions and meanings is important for all developers who wish to make the most of it.
1. Common Misconceptions Regarding React
React is Just a Library, Not a Framework
Many web developers think of React as just a JavaScript library, like jQuery. However, there is much more to React than that. As Facebook developers wrote in 2015 when introducing React: “React isn’t just a library – it’s an entire ecosystem.” React is based on the idea of building blocks rather than breaking things down into templates. Rather than trying to force developers to conform to a specific conventions or protocols, React is designed to be open ended and extensible, thus allowing developers to tailor their components to fit their own unique use cases.
React is Not Easy to Learn
Despite its many advantages, React can be intimidating to learn because of the sheer amount of concepts and paradigms involved. It’s true that learning the basics of React is relatively simple, but mastering it requires a lot of dedication and time. Furthermore, while React is a fairly accessible framework, its React Native cousin requires extensive knowledge of both Objective-C and Android Studio to get up and running.
React is Not for Small Projects
Many developers think that React is best suited for large-scale projects, like enterprise-level applications. However, this is not true. React can be used to build almost any type of application, from small modules to complex web apps. While applications that require extensive data manipulation might benefit the most from React, small projects can also benefit from its structure.
React Is Difficult to Debug
Because React applications are composed of loosely coupled components, debugging can be difficult. For instance, tracking down the source of bugs can be difficult given React’s strict one-way data flow. Additionally, debugging React applications on mobile devices can be tricky due to platform-specific quirks.
React Does Not Play Nicely With Other Technologies
Finally, many developers think that React is incompatible with other technologies. However, this is not true. React is designed to be flexible and extensible, and it plays nicely with many other web technologies, such as XHTML, CSS, and JavaScript. Additionally, React Native has excellent integration with native hardware and can be used to build cross-platform applications for both Android and iOS.

2. Problems with the React Framework
React Framework has a few drawbacks that cannot be overlooked when considering its usage. Even though it is highly efficient and robust, it has some areas that don’t quite measure up to its general performance.
Cluttered Syntax
React Framework is React-based and relies on JavaScript as its scripting language. The use of JSX instead of plain JavaScript can be a confusing thing for many developers as it has a very unique syntax and extra complexities. Additionally, many React elements are used in order to define a simple behaviour which can lead to it being more difficult to read.
Library Not Comprehensive Enough
The library of React Framework is not comprehensive compared to other frameworks such as Angular or Vue. This can create head-scratching situations while trying to build out a robust project and it can be difficult to navigate the web for 3rd party modules. On top of that, finding compatible modules could be a difficult task which may require extra research.
Overall, React Framework can be an efficient choice for most web projects due to its high performance, substantial library, and excellent documentation. However, the use of clichéd syntax, a need for complex React elements, and a lack of comprehensive modules should be taken into consideration when deciding which framework to use for a project.
3. Challenges Created by React Components
React components bring in a whole new set of challenges when developing applications. It is important to consider these challenges and think of ways to overcome them before writing code.
Managing State
One challenge with React components is managing the state within the components. Handling state correctly is critical for ensuring that components are reused or components properly communicate with each other. It is important to choose the correct state management library or framework when working with React components. Popular libraries and frameworks include Redux, Mobx, and GraphQL. Alternatively, one could manage the state within the component using the React setState() method or classes.
Testing
Another challenge with React components is testing. Component testing is critical to make sure the code works as expected. Unit testing each individual component provides the necessary coverage while integration testing provides coverage across components. Libraries such as Jest provide the necessary tools for testing React components easily and quickly. Additionally, component testing could be automated with frameworks such as Cypress.
In conclusion, managing state and testing React components present challenges when developing applications. It is important to consider these challenges and think of ways to overcome them before writing code. Popular libraries and frameworks such as Redux, Mobx, GraphQL, and Jest can handle a lot of the heavy lifting making React development efficient and enjoyable.
