Deep Dive into React States From Imperative to Declarative Programming
The evolution from imperative programming with vanilla JavaScript to modern JavaScript frameworks has revolutionized UI development. Imperative programming required detailed instructions to manipulate the UI, making it inefficient and difficult to scale as projects grew in complexity. Managing highly complex frontend projects was nearly impossible.
Modern JavaScript frameworks such as KnockoutJs, AngularJS, VueJs, and ReactJs were developed to shift from imperative to declarative programming. These frameworks allow programmers to specify what should be displayed, leaving the complex task of rendering to the framework. This shift enabled developers to focus on business logic, making it feasible to build and manage highly complex frontend applications.
React: A Modern JavaScript Framework
React is a popular and versatile JavaScript framework. It is unopinionated, meaning it provides tools and methodologies but leaves the implementation details to the developer.
Components in React
Components are the building blocks of a React application. A React app is divided into smaller, manageable, and maintainable pieces of code. Components have two key aspects: props and state.
- Props: Passes from a parent to a child component, props are read-only.
- State: Internal to the component and immutable, state can be changed using the setter function. Any change in state causes the component to re-render.
Principles of Structuring State
1. Group Related State: Combine related states. For example, instead of having separate states for longitude and latitude, combine them into a single state representing coordinates.
2. Prevent State Contradictions: If two states are interdependent and some combinations are impossible, derive one state from the other to avoid contradictions.
3. Eliminate Redundant State: If information can be calculated from props or component state, avoid adding it to the component state.
4. Avoid State Duplication: Duplication of data across multiple variables can cause synchronization issues. Maintain a single source of truth.
5. Minimize Nested State: Deep hierarchies are challenging to update. Prefer a flat state hierarchy whenever possible.
Sharing State Between Components
When state needs to be shared between components, lift the state to the closest common parent and pass it down via props. This technique is known as state lifting in React.
Extracting State Logic to Reducers
Managing numerous states and updating them through various event handlers can become complex. Extracting state update logic into a reducer, facilitated by the `useReducer` hook, helps manage this complexity.
Prop Drilling
As components grow in complexity, passing props through multiple levels becomes cumbersome. This practice is known as prop drilling. To address this, use React’s context. Context allows you to inject data at a higher level and access it in any child component without passing props through each level.
Combining Reducer and Context API
For effective management of a complex screen, combine the use of reducers and context. A reducer consolidates state update logic, while context allows you to pass data to deeply nested components without props. Inject the data via context at the root level, exposing both the data and the dispatch function to update the state.

Add React into Your Existing Project: A Step-by-Step Guide
ALTIf you’re looking for a JavaScript framework, React is your best bet. Quickly and easily create feature-rich web applications with its help. Additionally, it facilitates the integration of third-party components, such as the React image uploader, into your ongoing project.
It just takes a few lines of code. Because of this, things might become simpler for you. When attempting to incorporate React into an ongoing project, where does one even start, or should we hire reactjs team? This article has all the necessary information.
Would it really be that simple to incorporate React into an already-existing project?
Incorporate React into Your Current Project: Essential Resources
- Before you continue, make sure Node is installed on your computer. Feel free to get it from nodejs.org. You must be using Node version 10 or later.
- The following need is npm, the node package manager. Automatic installation on your PC will be done by Node. Make sure you’re using npm version 5.2 or later.
- Finally, a trustworthy code editor is a must-have. On the internet, you could discover a plethora of potential answers. Visual Studio Code is an intuitive editor. Its popularity among programmers is immense.
Use React in Your Existing Web App or Project
Applying a React component to an already-existing HTML page is the subject of this tutorial. Observe these procedures:
Step 1: Include the DOM container in the HTML
Start by opening the HTML page that you want to modify. Craft a div element devoid of any content. Show off the upgrades here by putting React to work.
Here we have the
<div id=”medium_blog_container”>
<! — Here we will mount our component →
</div>
Step 2: Add script or react tags
Next, you need to add three <script> elements to the HTML page before to the closing </body> tag.
Through the first two tags, React is loaded.
Step 3: Create the component code
A file called medium_post_component has to be included in your HTML page
React may be built in JSX or in a non-JSX format.
<!DOCTYPE html>
<title>Add React in One Minute</title
</head>
<body>
<;p>This page using React with no build tooling.</p> <p>React is loaded as a script tag.</p>
<!-we will put our React component inside this div. -><div id=”like >
<!Load React.
<h2>Add React in One Minute</h2>
<! <script “ <script “ crossorigin
-Note) when deploying, replace “development.js” with “production.min.js”,
<!-Load our React component,
<script >
</body>
Add React to Existing Project — Add JSX To A Project
No complicated tools, such as a bundler or development server, are required to incorporate JSX into a project. The method of including a CSS preprocessor is really very similar. However, Node.js has to be installed on your machine. It is very necessary.
Integrating JSX couldn’t be easier. Here are the basic procedures that must be adhered to:
Use the terminal to go to the folder where your project is saved.
Now, run the following command.
npm init -y
Execute the command npm init -y. In the event that the last attempt was unsuccessful, you may try this:
npm install babel-cli@6 babel-preset-react-app@3
That’s it! You now have a production-ready JSX setup in your project.
Add React to Existing Project — Run JSX Preprocessor
In order to start the JSX preprocessor, a folder called “src” has to be established. After that, type this into the terminal:
npm install babel-cli@6 babel-preset-react-app@3
Be wary of the following warning: “You have mistakenly installed the babel package”; it appears when you least expect it. You could have forgotten about the previous step. Running it in the same directory could make it work. It should fix the issue.
You are not need to remain still until the treatment is finished. With the aforementioned command, you may set up an automated watcher for JSX.
If you create a file in the src folder with the name like button.js, the watcher will produce that file. It will include simple JavaScript code that is compatible with browsers.
On top of that, you may use it to take advantage of the most recent syntactic advancements in JavaScript. You may use classes without worrying about compatibility issues with older browsers, for example.
Keep in mind that npx does not indicate an error. A package execution tool is pre-installed with npm 5.2+.
Add React to Existing Project — Using Fetch To Make HTTP Calls in React
The Fetch() API is available to browser users. With it, you may make HTTP calls. What follows is an analysis of the Fetch API’s standard syntax.
let response = fetch(
API_URL,
…. (some more options)
);
In this case, you’re calling the getNames function. It is able to retrieve data. On top of that, it gets other parameters, like —
- It’s a great way to tell what sort of HTTP request you’re getting.
- You may use it to set content request headers or permission headers.
- The “mode” property tells us whether the mode is cors or no-cors.
- You may send extra information to the server using the “body” component of a request.
To illustrate how a React component may use Fetch, consider the following:
async getName(){
//With .then and .catch section
let response = await fetch(“https://jsonplaceholders.com/users")
.then(resposne => {
return response.json();
setNames(response )
})
.catch(error => {
console.log(error);
});
}
Tips for Adding React to Existing Project
- Reuse a Component
You would want to have React components shown in several places on an HTML page. Here are the measures to take in that direction:
Navigate to the HTML file that you own. Insert the lines that follow:
<!DOCTYPE html>
<html>
<head>
<meta charset=”UTF-8" />
<title>Add React in One Minute</title>
</head>
<body>
<h2>Add React in One Minute</h2>
<;p>This page demonstrates using React with no build tooling.</p>
<p>React is loaded as a script tag.</p>
<p>
This is the first comment.
<! — We will put our React component inside this div. →
<div class=”like_button_container” data-commentid=”1"></div>
</p>
<p>
This is the second comment.
<! — We will put our React component inside this div. →
<div class=”like_button_container” data-commentid=”2"></div>
</p>
<p>
This is the third comment.
<! — We will put our React component inside this div. →
<div class=”like_button_container” data-commentid=”3"></div>
</p>
<! — Load React. →
<! — Note: when deploying, replace “development.js” with “production.min.js”. →
<script src=”https://unpkg.com/react@18/umd/react.development.js" crossorigin></script>
<script src=”https://unpkg.com/react-dom@18/umd/react-dom.development.js" crossorigin></script>
<! — Load our React component. →
<script src=”like_button.js”></script>
</body>
</html>
- Go to your JavaScript file. Insert this code:
const LikeButton = ({ commentID }) => {
const [liked, setLiked] = React.useState(false);
if (liked) {
return `You liked comment number ${commentID}`;
}
return (
<button onClick={() => setLiked(true)}>
Like
</button>
);
};
// Find all DOM containers, and render Like buttons into them.
document.querySelectorAll(‘.like_button_container’)
.forEach(domContainer => {
// Read the comment ID from a data-* attribute.
const commentID = parseInt(domContainer.dataset.commentid, 10);
const root = ReactDOM.createRoot(domContainer);
root.render(
<LikeButton commentID={commentID} />
);
});
Conclusion
Simply said, you have gained the knowledge necessary to incorporate React into an ongoing project. You also have a solid grasp of useful tips, such as how to reuse components and minify JavaScript so it’s ready for production. You may immediately start using React and hire reactjs developer for your next project to effortlessly improve your existing applications and include amazing features.

Vue.js vs Angular: The Best JavaScript Framework to Choose
Choosing between Vue.js and Angular is an important decision for any JavaScript project. Both frameworks offer a set of unique advantages and can be suitable for different types of projects.
Vue.js is a lightweight and flexible framework that’s easy to learn and quick to prototype with. It has a simple syntax and fast rendering capabilities, making it an excellent choice for small to medium-sized projects. Vue.js also has a growing community and an expanding ecosystem of third-party libraries and tools.
Angular, on the other hand, is a full-fledged development framework that offers a comprehensive solution for building complex and scalable applications. It has a more rigid architecture and a steeper learning curve but also provides a robust set of features and tools for enterprise-level projects. Angular has an established community and a vast ecosystem with extensive documentation and support.
In addition to project size and complexity, there are other factors to consider when choosing between Vue.js and Angular. For example, Vue.js is often preferred by developers who prioritize speed of development and flexibility, while Angular is favored by developers who value a more comprehensive and structured approach to development.
Ultimately, the choice between Vue.js and Angular depends on your project requirements and team expertise. If you’re working on a smaller project or prefer a more lightweight and flexible framework, Vue.js may be the best choice. If you’re building a larger and more complex application and require a more comprehensive solution, or if your team has experience with TypeScript, Angular may be the better option.
When choosing between Vue.js and Angular for your JavaScript project, there are several other factors to consider in addition to project size and team expertise. Here are some additional points to keep in mind:
Performance: Both Vue.js and Angular are designed to deliver high-performance applications. However, Vue.js is generally considered faster and more lightweight than Angular. This makes it a great choice for projects that require fast rendering and good overall performance.
Community Support: Both Vue.js and Angular have large and active communities that contribute to their growth and development. However, the level of support can vary depending on the region and industry. In some regions, Vue.js may have a stronger following and more active contributors, while in others, Angular may be more popular.
Tools and Libraries: Both Vue.js and Angular have a wide range of tools and libraries available to help developers build their projects. However, the availability and quality of these tools can vary between the two frameworks. For example, Vue.js has a growing ecosystem of tools and plugins, while Angular has a more established set of tools and libraries.
TypeScript: Angular has built-in support for TypeScript, a popular programming language that provides additional type-checking and other features. Vue.js, on the other hand, supports TypeScript through plugins and other third-party tools. If your team already has experience with TypeScript or values the additional type-checking it provides, Angular may be the better choice.
Developer Experience: Both Vue.js and Angular strive to provide a good developer experience, but the approaches they take can differ. Vue.js is designed to be easy to learn and use, with simple syntax and clear documentation. Angular, on the other hand, is designed to provide a more structured and organized approach to development, with a strong emphasis on architecture and testing.
In conclusion, both Vue.js and Angular are powerful and popular JavaScript frameworks, and each has its own set of strengths and advantages. By carefully considering your project requirements and team expertise, you can make an informed decision about which framework to choose for your next JavaScript project.

What exactly does the development of React Native apps mean?
React Native is a JavaScript framework that allows developers to build mobile apps for iOS and Android using a single codebase. It is based on Facebook’s React JavaScript library for building user interfaces, and allows developers to use the same approach for building mobile apps as they would use for building web apps. This means that developers can write mobile app code in JavaScript and reuse existing code from web projects, making the development process more efficient and cost-effective. Additionally, because React Native uses native components, apps built with it have a similar look and feel to apps built with traditional, platform-specific languages like Swift or Java.
