React Tutorial for Beginners

What is React?

React is an open-source front-end JavaScript library maintained by Facebook.

How is React used?

React allows developers to quickly create reusable user interface (UI) components for mobile or single-page applications.

What can you build with React?

Social media, e-commerce, and productivity apps can all be made in React, along with many other UI components.

For this React tutorial, we will cover the installation process, basic file structure, and DOM rendering.

What is required to use React?

React, similar to any other web framework, needs certain locally installed packages to work correctly.

To follow this React tutorial, you need to:

  • install Node.js
  • install npm
  • install and configure create-react-app

You do not need any prior experience with React to follow the React tutorial below.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Data Visualization in R with ggplot2: A Beginner Tutorial

A famous general is thought to have said, “A good sketch is better than a long speech.” That advice may have come from the battlefield, but it’s applicable in lots of other areas — including data science. “Sketching” out our data by visualizing it using ggplot2 in R is more impactful than simply describing the trends we find.

This is why we visualize data. We visualize data because it’s easier to learn from something that we can see rather than read. And thankfully for data analysts and data scientists who use R, there’s a tidyverse package called ggplot2 that makes data visualization a snap!

In this blog post, we’ll learn how to take some data and produce a visualization using R. To work through it, it’s best if you already have an understanding of R programming syntax, but you don’t need to be an expert or have any prior experience working with ggplot2

React Hello World: Your First React App

The best way to learn React is to re-create Hello World but for React. Let’s learn all there is to know about building a simple Hello World app in React!

What We’re Building

This tutorial will thoroughly explain everything there is to know about creating a new React app in the quickest way possible. If you’re someone who wants to learn how to spin up a brand new React app, then this tutorial is for you.

I’ve summarized the most important details for each step under each of the headings so you can spend less reading and more coding.

Generate a New React App Using Create React App

  • Create React App (CRA) is a tool to create a blank React app using a single terminal command.
  • CRA is maintained by the core React team.

Configuring a _modern _React app from scratch can be quite intricate, and requires a fair amount of research and tinkering with build tools such as Webpack, or compilers like Babel.

Who has time for that? It’s 2019, so we want to spend more time coding and less time configuring!

Therefore, the best way to do that in the React world is to use the absolutely fantastic Create React App tool.

Open up your terminal and run the following command:

Terminal

npx create-react-app hello-world

This generates all of the files, folders, and libraries we need, as well as automatically configuring all of the pieces together so that we can jump right into writing React components!

The success screen after scaffolding a new React app with Create React App. Let’s get hacking some React components together!

Once Create React App has finished downloading all of the required packages, modules and scripts, it will configure webpack and you’ll end up with a new folder named after what we decided to call our React project. In our case, hello-world.

Open up the hello-world directory in your favorite IDE and navigate to it in your terminal. To do that, run the following command to jump in to our Hello World React app’s directory.

Terminal

cd hello-world
