Welcome back to another React tutorial! In this video, I’ll be showing you how to style the website we’ve been working on. There are a bunch of different methods for styling in react that I’ll go over.

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.

Does this sound like you? Because this is exactly how I felt when I started learning React. All I wanted to do was set up a simple React app, and I was getting very confused. I thought React had a fairly difficult learning curve, and I was feeling pretty overwhelmed.
This is what I would have liked to have known before I began writing a single line of React code:
First, let’s nail out the basics. Before you start diving into React, you should probably have at least a little experience with each of the following:
- NodeJS + NPM
React has 4 ideas that are key to getting started learning with React.
If you create a component for a share button, you can reuse that component to build other share buttons, or reuse it across multiple different kinds of articles. This is the idea with React. You are building components that then can be used and reused to build bigger components.
Props is short for properties. Properties are how you pass information unidirectionally from parent to child components. I like to think of them as property attributes or parameters, since it is conceptually similar to passing arguments into a function, and syntactically similar to HTML attributes. Look at the example used previously. If this were a React component, the props would be what you are passing in as “src”, “alt”, “height”, and “width”. You can also pass in callback functions for the child to execute such as “onClick”.
Many React components will be stateful components. State is exactly what it sounds like. It’s the internal state of your component. Think of a checkbox on a web page. It can either be checked or unchecked. When the user clicks on the checkbox, it will check the box if it is unchecked, and when the user clicks it again it will uncheck the box. The checkbox is an example of a stateful component. In this example, the internal state of the checkbox would be a boolean that would either be checked true or checked false.
While many components have state, some are stateless. Just because lots of components have state doesn’t mean that every component needs to be stateful. Sometimes it makes sense to omit state from a component. Think of an image html tag.
**<img src=”smiley.gif” alt=”Smiley face” height=”42" width=”42">**
If this image tag would be an example of a stateless component. You are passing in parameters, but the image tag itself does not have an internal state that it needs to manage itself.
React is much easier to understand if you have a basic idea behind the React component lifecycle. The React lifecycle describes when and how a component should mount, render, update, and unmount in the DOM. React has lifecycle hooks (React component methods) that help you manage state, props, and work with the lifecycle flow.
**React component lifecycle has three categories **— Mounting, Updating and Unmounting.
2. The componentDidMount() happens as soon as your component is mounted.
3. The componentDidUpdate_() _happens as soon as the updating happens.
4. The componentWillUnmount_() _happens just before the component unmounts and is destroyed.
5. The shouldComponentUpdate_() _can be used rarely.
6.The two new lifecycle methods are getDerivedStateFromProps() and getSnapshotBeforeUpdate().

These are only the basics to get started.

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).

To keep things simple and concise, we’ll start fresh with npx create-react-app dark-toggle . While we’re in our command line, let’s get the npm packages out of the way as well:
npm install styled-components styled-theming redux react-redux
styled-components: we’ll use this library to create isolated components that encapsulate their own styling
styled-theming: this library offers a very clean API to work with multiple themes in your styled components
redux and react-redux will do the heavy lifting regarding state management
#styled-components #react #react-hook #dark-theme #redux #react-native
In this article, you will learn what are hooks in React JS? and when to use react hooks? React JS is developed by Facebook in the year 2013. There are many students and the new developers who have confusion between react and hooks in react. Well, it is not different, react is a programming language and hooks is a function which is used in react programming language.
