What should I learn before starting with React.JS?

Defining React.JS

React.JS is an open source JavaScript library for creating user interfaces. It is commonly used as a basis for building interactive web applications. It is a component-based approach and a powerful tool for building dynamic user interfaces. React is designed to be used in combination with other libraries and frameworks, like Redux and Relay. It is used by companies such as Facebook, Instagram, Airbnb, and Netflix.

Components: React components are self-contained units that can be used in other parts of the application. They are a combination of HTML, JavaScript, and CSS that can be reused and customized. Components help developers to create complex applications by breaking them down into smaller, reusable pieces.

Virtual DOM: React works with a virtual Document Object Model (DOM). It keeps track of changes made by the user and updates the DOM in the most efficient way possible. This allows developers to create fast and responsive applications built on React.

Getting Started with React

JSX: JSX is a syntax extension for JavaScript. It is used within React components to define their structure and behavior. JSX combines markup and JavaScript code to create building blocks for React components.

Props: Props are immutable data that is passed to a React component from its parent component. Props are used to send data to components and to trigger a response. Props can also be used to create tight coupling between components.

State: State is mutable data that is used to store information inside a component. It is managed internally by React and can be used to store and retrieve information about the component.

React Lifecycle: React Lifecycle is the order in which a React component is created, updated, and destroyed. It consists of several phases such as mounting, updating, and unmounting. React Lifecycle allows developers to control when certain actions occur in a component.

React.JS: How Learning the Basics Can Open New Possibilities

React.JS: How Learning the Basics Can Open New Possibilities

A Guide to Learning the Fundamentals of React.JS

The React library is one of the most popular JavaScript libraries available, and has been around since 2013. It is used extensively in developing web and mobile applications, and is a key factor in many successful projects. Learning to use React can be a bit of a challenge, especially if you are new to JavaScript, but once you have mastered the basics, it can open up new possibilities for front-end development.
First and foremost, React works on the principle of breaking down complex code into smaller, manageable components. This makes it easier to develop and edit code, and encourages code reuse. By breaking down the code into logical components, you can also re-use the same code in different applications, which can improve the speed and efficiency of development.
In addition to breaking down complex code, React also relies on the use of JavaScript, which is the main language for client-side web applications. JavaScript is used to define the components for the web application, and the data that is exchanged between the components. Therefore, it is important that developers have some familiarity with this language, as well as with HTML and CSS.
React also implements a “virtual DOM”, which is used to represent the application state. This allows for a more efficient way to update the application state, as changes to the DOM are tracked by the virtual DOM, and the web application can be updated with minimal effort. Furthermore, React also includes support for components — which makes it easy to create complex user interfaces quickly.

The Aim is Simplicity

The goal behind React is to make developing web applications simpler and faster. By utilizing the components of React, code can be quickly and easily written and maintained, without having to write complex JavaScript code. By using the virtual DOM and component architecture, React applications are also more efficient, as the same code can be used for different applications.
Finally, React also has a library of JavaScript libraries and frameworks, which makes it easier to utilize specific features or plugins. There are also a large number of libraries and frameworks available for React, such as Redux, MobX, React Router, and more, which can be used to make developing applications easier.

Important Things to Consider

Before getting started with React, there are a few important things that developers need to take into consideration. First, it is important to have some familiarity with the three core web technologies (HTML, CSS, and JavaScript), as these are fundamental for the development of React applications. Secondly, it is also important to understand the fundamentals of the React library — such as the virtual DOM, components, and the libraries and frameworks associated with React.
Finally, it is important to have some knowledge of the tools and libraries available for React. This includes popular libraries such as React Router and Redux, which can help to create powerful web applications.


Learning the basics of React.JS can open up a whole new world of possibilities for front-end development. By understanding the core concepts of React, as well as the tools and libraries available, developers can create powerful web and mobile applications quickly and efficiently.

Unlock the Potential of React.JS: Where to Start Learning?

Gaining an Understanding of React.JS

Getting started with a new technology can be intimidating to many, especially if that technology is as popular and powerful as React.JS. It isn’t always easy to find the information needed to confidently and competently work with React.JS, so the question becomes: where does one begin? With just a few simple steps and knowledge, React.JS can unlock a world of potential for web developers of any level.

Discovering the Building Blocks of React.JS

To truly understand and properly use React.JS, knowledge of the JavaScript language is essential. Without JavaScript experience, React.JS can feel like a daunting task that is difficult to make sense of. After gaining an understanding of JavaScript, a firm grasp of the core React.JS building blocks takes a bit of time and practice.
The two main building blocks of React.JS are components and properties, both of which have a profound impact on the look and operation of an application. Components are essentially code blocks that are used to create different elements. Through components, developers can make a page reflective of their vision and also structured in a well-written, effective way that is easy to read. Properties enable developers to shape their components in a variety of ways including creating custom styling, as well as tracking and transferring component state.

Putting React.JS Knowledge to Use

When it comes to using React.JS, it is best to start with creating a simple application and working gradually from there. After creating an environment where React.JS can be explored, the JavaScript language needs to be studied, which will also help familiarize users with components and properties. Once the two main building blocks of React.JS are understood, more involved and complex applications can be created with more confidence.
To get the most out of React.JS, developers need to get to a point where they truly understand and can find their way around the framework that is set up for them. Thankfully, it doesn’t take a great deal of prior knowledge to make use of React.JS – as long as developers can get their footing in JavaScript and the core sections of React.JS, the potential is truly unlimited. Learning React.JS can be a fulfilling journey for developers of all levels, with an abundance of resources available for those who are eager to learn.


With the rise of front-end development and the increasing prominence of web-based applications, many developers are looking for a way to make their projects more contemporary and engaging. React.js is one of the most popular frameworks available for doing this, but before delving into React.JS, one important question should be asked: what should developers learn before starting?
