What is React and Why Should You Care?

Building a website that stands out is as difficult as starting a business. Even more difficult. This is where the JavaScript library React comes in, which makes it easy to create websites that are quick, interactive, and easy to use. As a business owner, I recall being intimidated by technical terms when I first learned about React. The problem is that React isn't limited to developers. This tool can assist you in developing a vibrant online presence that generates leads and increases sales. At Fykel's services, we use React to create high-performing, reasonably priced web apps that produce tangible business outcomes.

Facebook created React, which enables you to create reusable elements that give your website a responsive, modern feel. Comparable to Lego blocks, each component fits together to form a unique whole. Why is this important? Because a quick and interesting website keeps users interested, boosts search engine optimization, and converts clicks into sales. Are you prepared to start using React? Let's keep it easy and enjoyable.

Setting Up Your React Environment

You must have the proper setup before you can begin coding. To be honest, I was intimidated when I first attempted to set up a development environment. It was like putting together furniture without a manual. But believe me—especially with today's tools, it's not as difficult as it looks. Here's how to begin using a cost-effective React development setup.

Node.js, which includes npm (Node Package Manager), is required first. Get it at nodejs.org.For stability, choose the LTS version. After installation, use the following commands in your terminal to make sure it's functioning:

node -v
npm -v
    

Next, set up your project using Create React App. The heavy lifting is done by this user-friendly tool for beginners. Execute this command:

npx create-react-app my-first-react-app
cd my-first-react-app
npm start
    

Wow! Your browser should launch a React starter app at http://localhost:3000. This setup is ideal for creating a distinctive business website that generates leads, and it's quick and free. For examples of React-powered websites, visit Fykel's portfolio.

Building Your First React Component

The core of React is its components. Consider a button, navbar, or product card as examples of the tiny building blocks that comprise your website. It's thrilling to create your first component, but I'll be honest: it can feel strange at first. I kept asking myself, "Why can't I just write plain HTML?" when I first started. But once you get the hang of components, you’ll see how they make your site scalable and maintainable.

Let's make a basic part. Make a file named Welcome.js in the src folder of your project, then insert the following code:

import React from 'react';

function Welcome() {
  return (
    

      
Welcome to My Business Site!
      
Boost your leads with a modern React website.
    
  );
}

export default Welcome;
    

Now, import and use it in src/App.js:

import React from 'react';
import Welcome from './Welcome';

function App() {
  return (
    

      
    
  );
}

export default App;
    

After saving, a greeting header and paragraph ought to appear in your browser. Since this element is reusable, consider utilizing it on several pages to maintain the consistency of your branding. This allows business owners to spend more time on expansion and less time adjusting designs.

Managing State and Props in React

This is where React becomes strong—and a little challenging. You can make your website interactive by using state and props. This also didn't make sense to me at first. "Why can't I just update the page directly?" I kept asking myself. But bear with me—after you grasp state and props, you'll see how they contribute to the dynamic and captivating nature of your website, which is essential for drawing in leads.

What Are Props?

Props, short for properties, allow you to pass information to components. Consider them to be function arguments. Make changes to your To accept a prop, use the code Welcome.js:

import React from 'react';

function Welcome(props) {
  return (
    

      
Welcome, {props.businessName}!
      
Boost your leads with a modern React website.
    
  );
}

export default Welcome;
    

In App.js, pass a prop like this:

import React from 'react';
import Welcome from './Welcome';

function App() {
  return (
    

      
    
  );
}

export default App;
    

Your component now shows "Welcome, Your Awesome Startup!" Props give your components flexibility so you can use them again with different data, which is ideal for making pages that are distinctive and branded.

What is State?

State is how you handle data that is subject to change, such as a form input or counter. To add interactivity, use the useState hook. A counter component in a new file, Counter.js, looks like this:

import React, { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);

  return (
    

      
You clicked {count} times
       setCount(count + 1)}>Click me
    
  );
}

export default Counter;
    

Add it to App.js:

import React from 'react';
import Welcome from './Welcome';
import Counter from './Counter';

function App() {
  return (
    

      
      
    
  );
}

export default App;
    

There is now a button on your website that can be clicked to update the count. In order to convert visitors into leads, this type of interaction keeps users interested. The fundamental components of dynamic, reasonably priced React apps that propel company expansion are state and props.
