Before plunging into the realm of React with JS frontend development, you should understand everything there is to know about JavaScript and the React framework.
There are several JS frameworks available, but React and JavaScript have proven to be excellent frontend development partners throughout the years.
If you are new to programming, sticking with the most popular frontend framework will guarantee you a successful future in both online and mobile app development. Nothing beats the combination of React with JavaScript, so if you’re as enthusiastic as we are, let’s keep learning more about these concepts.

What Is React? What Is JavaScript? Could the Answers be Any More Obvious?!
We realize the answers are extremely apparent, but please forgive us because we need to convey the principles to our non-developer readers. So, if you are a project stakeholder who wants to learn more about React and JavaScript, here are some topics to consider.
JavaScript is essentially a client-side programming language used to manipulate UI components, provide dynamic features to the page, and attract more visitors. Although JS is a versatile language that can be displayed on a variety of libraries and frameworks, React is the developer’s prince charming.
React JS is the most popular frontend library, with a devoted and active user base. It is open-source, lightweight, quick, and adaptable, with several added features. The extensive libraries and reusable components in React will make the developer’s job easier.
The fantastic React features several efficient APIs, and everything in React can be tweaked.
If you have faced any issues in web development with React, you can use some other libraries and frameworks as the solution.
When the browser gets React’s JSX file, the integration of React with JS begins at the heart of the web-building process, in HTML codes.
Introducing JSX, Its Functions, and Specifications
React introduced a new authoring format for JavaScript code: JSX, a blend of JS and XML. The end result is a syntax that is comparable to HTML yet can render JS scripts while avoiding its complications.
Because the browser does not recognize JSX, you will need a compiler to convert the JXS codes into a browser-compatible format. The goal of utilizing JSX is to help React with the Virtual DOM paradigm.
What Is Virtual DOM, and How Is It Related to JSX?
The Document Object Model (DOM) is an API that organizes HTML data (UI components) into a logical structure that can be readily modified. The DOM function would make it easier to make changes, update data, and retrieve stuff. React’s library will be like a highly-organized drawer where one can find things easily.
React and JavaScript pushed their collaboration to the next level by introducing the Virtual DOM method. Because JSX’s role is to write HTML elements in the VDOM, React has a copy of the real DOM and can modify data more quickly and easily.
Aside from VDOM and its advantages, the biggest advantage of utilizing JSX is that you can watch your JS code as it renders. The combination of React and JavaScript is ideal for streamlining the web app development process.
The development process will become considerably easier in the initial phase of React’s interaction with JS, but React’s value lies in its modular, reusable components. Let’s go deeper into its coding process and component management.
React with JavaScript Components
React provides several methods for ordering, managing, and modifying JavaScript components. In this section, we’ll look at how React handles various JS components.
Big Components and Its Challenges
It is hard to handle and understand big components; thus, the best solution is to break down the big components into smaller and reusable ones.
In your web project, for example, if you have a navigation bar with certain buttons, you may divide them into different child components. Each child component, such as the Home and About buttons, can have distinct states and requirements.
Nesting Components
When you have multiple components and divide them down into smaller components, you may have performance concerns. As a result, when you render the parent component function, the child’s function is also presented. To address these concerns, create the child component individually and then add a prop to handle data flow.
What Is a Prop?
Before we go into the other benefits of React with JS components, let’s define a prop. As we all know, React is a framework that is well-known for its ability to manage and render data in a fluid manner.
Let me illustrate the topic with an example: imagine you need to gather the names and surnames of users in your application. As a result, you may create a component with the name and surname values; this fixed information in the components is referred to as states. You will define the function directed to the states using the props.
The prop is in charge of taking or altering the name and surname as needed. Props are an abbreviation for properties; they are parameters to components that fetch and send data from one component to another in order to maintain the app’s dynamic flow. If the props change or we specify a new one, the component will be displayed in a different way.
React and JavaScript Generate Complex Components
In some situations, you may need to define some sibling components but defining a child component without a root element is impossible. Therefore, you can use the in-built fragment feature of React to define another child component.
As your app grows, the components will be more and more complicated; thus, you can define each component in one separate file. If you wish to avoid multiple import/export commands, you’d better designate one specific directory for each component.
Prop Drilling in React with JS Components
If you are not utilizing Redux as your state management solution, you will need to send the state via all the components in between if you need to establish a child component with the parent component’s state.
If you want to learn more about Redux and React, we have a detailed post on the subject.
Use JavaScript Bundles to Solve the Complexity Issues
The app will ideally expand, thus you’ll need certain tools to help you with the job. As the program grows in size, you save more JavaScript codes, thus you’ll need something to help you with the work.
React has a lazy loading mechanism that allows you to split components into JS pieces. As a result, the browser will display any component that is requested. Webpack, Rollup, Parcel, and Browserify are bundlers that can combine the separated JavaScript scripts.
This feature will improve the app’s efficiency since the browser will run quicker, and this testifies to the fact that React and JavaScript find ways to get along in efficiency and compatibility.

JavaScript web apps leverage the power of React’s component-based architecture and JavaScript’s versatility to create seamless user experiences, enhance performance, and enable smooth interaction with backend services.
With the ability to handle complex logic, manipulate data, and respond dynamically to user actions, JavaScript empowers web apps to deliver exceptional functionality and responsiveness, making them an ideal choice for modern, interactive applications.
frequently asked questions
React employs JSX (JavaScript plus XML), a syntax that is essentially HTML written in JavaScript. To study JSX and determine if faults in your application are connected to JavaScript or to the more specialised area of React, you need be familiar with both HTML and JavaScript.
In comparison to more conventional JavaScript frameworks, this makes React programmes considerably quicker. Furthermore, React may be used with other libraries and frameworks to produce even more robust software. For these reasons, React is a great option for developing fast and responsive user interfaces.
Start Your JSX In React!
React with JavaScript is ready to work its magic, and the app should be up and running as soon as feasible. React with JS integration simplified web development and gave React greater flexibility.
Its novel syntax has made it possible to create reusable components and has broadened the breadth of React’s library. Reusable components not only aid developers with their projects, but they may also benefit the React user community.
For creating a dynamic and responsive user interface, using React and JavaScript may be the ideal option. If you have any React expertise, please share it with us, and if you are interested in web development using React, please contact us.
