The smallest React example looks like this:
ReactDOM.render( <h1>Hello, world!</h1>, document.getElementById('root') );
It displays a heading saying “Hello, world!” on the page.

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.
Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.
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:
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:
Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

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!
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.
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:
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.
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

Every component in React goes through a lifecycle of events. You can think is of going through a cycle of birth, growth, and death the same as the picture below.
This is the phase in which the component is going to start its journey. The developer has to define the props and initial state of the component. This is usually done inside the constructor method (see below to understand the initialization phase better).
