Knowing how they work at a high level is always helpful to debug your environment in case you run into issues.

📘 How to Deploy, Host, and Make Your App Public:

It won't be much fun if you have created something cool with ReactJS and cannot showcase it to the world. So, you should know how to deploy the app and make it available for public access.

Tools like Vercel or Netlify makes it easy to deploy your React app with a few clicks.

📘 What to Learn as a Beginner to React

Let's now focus on what you need to learn at the minimum to start enjoying React in practice. These are foundational pieces, so make sure to give enough time and hands-on effort to truly understand the concepts.

There is a famous saying called "Think in React". These fundamental concepts should help you to develop that "Think in React" mindset.

📘 Understand What React Is

You should understand what is so special about ReactJs. It is a declarative, component-based user interface library.

📘 Learn How to Set Up Your Development Environment

Setting Up Your Playground: A Quick Guide

Getting your playground ready for ReactJS is the first step. There are a few ways to do this, but let's keep it simple.

At the very beginning, you can just connect your HTML file to a React library online using a link. It's like borrowing a book from the library to read. This gets you started quickly, but it's not the best for the long run.

As you get more into React, you might hear about things like Babel and Webpack. They're like magic tools that help your code work better. But don't worry about them too much when you're just starting. You can dive into them later when you're more comfortable.

So, start with the simple setup, and as you get more experienced, you can explore the fancier tools. It's all about finding what works best for you and your projects.

📘 Exploring JSX

In ReactJS, we have a nifty tool called JSX. It's like a special language that mixes the best parts of HTML and JavaScript. Imagine you're building a puzzle – JSX lets you put the pieces together in a really smart way. You can talk about how things look and also make them work like magic, all in one place. It's like having your cake and eating it too! Without JSX, it's like building the puzzle without the cool picture on the box – doable, but not nearly as much fun. So, with JSX, creating in React becomes a breeze, and your projects become even cooler!

📘 State in React

Understanding State in React: Your Component's Private Playground

In React, "state" is like a secret playground just for your component. It's where your component keeps its special data – things it wants to show and change. This state is not shared with other components; it's like your component's private stash. So, when you want to show something or change something in your component, you play with its state. It's like having your own set of toys that only your component can use. Cool.

📘 Props in React

In real-world programming, you will need the components to interact with each other. States are private to a component, but you need to pass the data between components. That's where Props come into the picture. Note that props are read-only.

📘 Lists and Keys in React

We use list to render a list of items in a React component. It is a very common task to list users, TODO items, and other things. We use the map() function to iterate over the list and render the results.

📘React's Life Cycle

Remember, "state" is like a component's hidden treasure. When it changes, components need to tidy up. That's where "life cycle methods" step in.

Think of them as signals for components – from birth to exit. They help manage state, keep things organized, and handle tasks. When starting with ReactJS, focus on functional components' life cycle using tools like useState, useEffect, and more. These helpers ensure smooth component journeys, keeping everything in check.

📘 Styling Your React Creations

Everyone loves a good-looking app, right? When it comes to styling your ReactJS masterpiece, you've got options.

You can stick with regular CSS to make things pretty. Or, if you're feeling fancy, try Sass or other cool tools like TailwindCSS, ChakraUI, react-bootstrap, or MUI. It's all up to you – pick what makes your app shine!

📘 Form Handling in React

Forms are like the heartbeat of web apps – they're everywhere! So, getting a grip on how to handle them in ReactJS is a must.

You'll dive into the React way of dealing with form elements, mastering the art of form handling to keep your app pumping smoothly.

📘 Navigating Data in React

Time to tackle a biggie – handling data in your app. This is like the backbone of app development.

You'll dive into using the fetch API or cool libraries like node-fetch and Axios. These tools help you talk to other programs (APIs) and bring data into your app. It's like making friends with other apps and sharing toys. Get ready to master data handling like a pro!

📘 Reconciliation Process in React

ReactJS uses the Virtual DOM and diffing algorithm to decide when and what to update in the actual DOM for the rendering. Knowing how it works under the hood will help you with debugging.

📘 React Hooks Unveiled

Remember those cool helpers like useState and useEffect that we talked about while exploring the component's life cycle? Well, there's more where that came from!

React has other handy built-in hooks waiting to be your development buddies. They come with special abilities for specific tasks. Don't give them the cold shoulder – make friends with hooks like useContext, useRef, useCallback, and more. Each one has its own unique powers, so don't miss out on getting to know them!

📘 Custom React Hooks

Custom hooks help in reusability. You must look for opportunities to extract component logic to reusable hooks. The code becomes clean and modular with the usage of custom hooks.

📘 Context in React

Context helps you share important stuff across your app, even if components aren't directly connected. It's like having a magic carrier pigeon that delivers messages wherever you need them. So, when notes need to travel far and wide, call upon the Context to save the day.

How to Move from Intermediate to Advanced React Developer

In this phase, you will deal with a few expert-level topics. You need to know these concepts only when you're working on more extensive application development using ReactJS.

Note that you can learn each of these concepts whenever you're ready. Also, you don't have to learn them all.

📘 Lazy Loading

React supports a smart trick called code splitting. It helps you load only what's needed for a particular user, avoiding big bundles. Use dynamic imports to achieve this and keep your app snappy.

📘 Portals In React

When dealing with pop-ups like modals or tooltips, React's Portals come in handy. They handle these overlays with grace and are built right into ReactJS.
