Have you ever asked yourself if having knowledge of JavaScript is necessary to study React? Will you be able to use React without knowing JavaScript? How challenging is it to move towards React without a fundamental understanding of JavaScript?
As it is evident from the numerous discussions related to this topic on forums and blogs , the majority of users agree that having some working knowledge of JavaScript is very important if one wants to understand React. Although React is not a JavaScript library, it is usually used to work with JavaScript. Therefore, one must be familiar with the language’s features and know how to make use of the tools that JavaScript provides in order to use React effectively.
In this article, you will learn why having a basics of JavaScript is necessary to work with React, why it is beneficial to learn JavaScript before React, and what the main challenges are when using React without a solid understanding of JavaScript. Various techniques and strategies to bridge the gap between JavaScript and React will also be presented. Lastly, this article will discuss some of the best practices for learners to maximize their React learning experience.Definitions: React vs. JS
React is an open-source JavaScript library used for building user interfaces. It’s created and maintained by Facebook and a group of developers, providing a component-based structure that makes it easy to split out code and create reusable components.
JavaScript (or JS) is a scripting language that is used for creating and controlling the design and functionality of websites. It’s also used for game development, creating mobile applications, and manipulating databases. JavaScript code is written within HTML and can be embedded into web pages.
React and JavaScript are different in both purpose and design. React is a library and provides a structure for building user interfaces, while JavaScript is a scripting language used to create and control functions on websites. React focuses on individual components, while JavaScript is used to control many aspects of a website. Although both React and JavaScript have different applications, both are necessary for building websites and user interfaces. React provides a structured framework for code reuse and readability, while JavaScript provides the functionality necessary for websites and applications.
In order to use React, a basic understanding of JavaScript is required, as it is the language of React’s structure and syntax. However, it is possible to learn React without a deep knowledge of JavaScript by using third-party libraries and tutorials. React also requires a library of components for it to function correctly, so learning how to build and maintain them is critical for those intending to use React.
Overall, React and JavaScript are two separate but related technologies that are essential for creating user interfaces and websites. React provides a structured framework for code reuse and readability, while JavaScript provides the functionality necessary for websites and applications. Understanding both React and JavaScript is key to creating successful user interfaces and websites.
Introduction
Table of Contents
No, you do not need a comprehensive understanding of Javascript to study React. React is a JavaScript library used to create user interfaces. The library simplifies the process of creating and maintaining large web applications into components. It’s also compatible with a wide range of libraries and frameworks such as AngularJS and Vue.js.
Pros of React
React makes code more readable and maintainable, allowing developers to reason about a user interface more easily. Additionally, it is very fast and can render updates quickly, thanks to virtual DOM. React also has an enormous ecosystem with an abundance of resources and community support.
Cons of React
One of the biggest disadvantages of React is its steep learning curve. It can be difficult for those just beginning to learn React due to the library being component-based and driven by HML and JavaScript (JSX). In addition to this, React is open source, so platform and language documentation from someone outside of the library can be unreliable compared to other libraries.

1. Overview of JavaScript
Javascript is an interpreted programming language that is commonly used to implement functionality in websites such as games, videos, interactive 3D graphics, and more. It enables dynamic content which broadens the capabilities of websites, making them more interactive and engaging. JavaScript is a lightweight, interpreted programming language that is used for client-side scripting, which enables HTML documents to be interactive.
Features of JavaScript
One of the major features of JavaScript is that it is a client-side language, which enables the browser to run the code without the need of a web server. Javascript can interact with the HTML document or DOM and modify the elements in the DOM. It also allows developers to write more complex code and build dynamic websites using programming logic.
JavaScript Libraries
In addition to core JavaScript, there are also a number of JavaScript libraries that have been released in recent years. These libraries provide developers with pre-written code that makes it easier to implement certain functions and features in their websites. Examples of popular JavaScript libraries include jQuery, AngularJS and React.
Learning JavaScript is not a requirement for learning React since React is a library, not a language. However, understanding the basics of JavaScript will certainly make understanding React easier. Many of the features of React are built using JavaScript and understanding how it works will be helpful in learning and mastering React.
2. React vs JavaScript
React is a JavaScript library for building user interfaces. React can be used as a base in the development of single-page or mobile applications. It was developed by Facebook and is used by Facebook, Apple, Netflix, and several other large-scale interactive websites. React focuses on the view layer, allowing developers to easily create stateful and reusable UI components.
What Is JavaScript?
JavaScript is a scripting language used mainly for front-end web development. It is mainly used for creating websites and web applications that can interact with the user in a dynamic, interactive way. JavaScript is used to manipulate web pages, to build dynamic web applications, and to create mobile apps. JavaScript is versatile and can be used on server-side applications such as MongoDB and Node.js as well.
How React Differs from JavaScript
Although React is a JavaScript library, its syntax and development approaches differ. React deals with components and has its own component-based architecture. Components are standalone pieces of code that are composed to create applications. Components receive data, decide how to render the data, and respond to user input or interactions. React also utilizes a virtual DOM, which is a JavaScript object/tree structure of all the DOM elements. React creates and keeps track of this virtual DOM to update the actual DOM only when necessary, thereby increasing its speed and efficiency.
React also focuses on the use of functions rather than classes for creating components. This is an important distinction in JavaScript development, as functions are faster to execute than classes which can carry more complex logic and require more memory space. React also emphasizes the use of declarative programming, which makes coding easier and faster for developers.
In conclusion, React is a JavaScript library and it differs from JavaScript in terms of syntax, development approaches, and focus. React is focused on components, functions, and declarative programming. Knowing JavaScript is not necessary for studying React, but it is highly advisable as understanding the language is very important for React development.
