React and JavaScript are two technologies that are inseparable in modern web application development. React is a JavaScript library built on the programming language's foundation. JavaScript leverages its powerful features to create interactive user interfaces. Why do these two different technologies make an interesting combination? Let's take a closer look in the article below.
1. Difference between React and JavaScript - two independent technologies
React (2013) and JavaScript (1995) are different concepts in the realm of programming. Below are the differences between React and JavaScript.
1.1. React - JavaScript library for developing user interfaces
React is a powerful JavaScript library widely used to build user interfaces in web applications. Developed by Facebook, React makes it easy to build reusable UI components and manage application state.
React uses a "component-based" model, which divides the user interface into independent components. Each component has its own state and can receive external input. These components can be combined to create complex user interfaces.
One of React's strengths is its Virtual DOM. This is a copy of the actual DOM. When there is a change in the state of your application, React creates a virtual DOM tree and compares it with the real DOM tree. React then updates only the parts of the actual DOM that have changed, without having to re-render the entire interface. This improves performance and speeds up your application.
React also provides functionality for routing, state management, and more through libraries and frameworks like React Router and Redux.
With a large developer community and continuous updates, React is popular and widely used in modern web application development. React allows you to optimize your development process, improve reusability, and provide a great user experience.
1.2. JavaScript - general purpose programming language with usability
JavaScript is a general-purpose client-side programming language widely used for developing web applications. Originally created to run in a web browser, it has now become an essential element in creating interactive, dynamic, and flexible web pages.
JavaScript provides developers with a variety of tasks, including handling user interactions, modifying the content and interface of web pages, interacting with data and APIs from servers, and creating dynamic effects on web pages. Masu. It supports a syntax that is easy to read and understand, allowing you to develop complex web applications without relying on server-side programming languages.
Initially developed to perform tasks on web browsers, JavaScript has evolved significantly and has expanded to include not only web development, but also mobile app development, gaming, server-side, Internet of Things (IoT), and more. Used in various areas.
JavaScript has popular libraries and frameworks such as React, Angular, and Vue.js, which provide powerful tools and frameworks to help you optimize your development process and build efficient web applications.
2. React and JavaScript - Strength of cooperation in web application development
React and JavaScript are a powerful combination for developing web applications. Together, the two allow you to take full advantage of the capabilities of both to create powerful and flexible web applications. Below are some of the strengths of combining React JavaScript:
2.1 Application state management
React provides state management for web applications through the use of stateful components. JavaScript supports handling and updating this state. Effective state management makes application maintenance and expansion easier.
2.2. API Integration
JavaScript is a powerful language for interacting with APIs from servers. When developing web applications using React, JavaScript can call APIs, make requests, process returned data, and update the user interface.
2.3. Event handling and user interaction
JavaScript makes it easy to handle events and interact with users. React allows you to use JavaScript to handle events such as clicks and inputs, make requests to the server, and more. This allows for smooth and responsive user interactions.
2.4. Reusing components
React uses JavaScript syntax to create reusable interface components. JavaScript supports writing reusable code and building flexible and powerful components. This improves the efficiency of web application development and maintenance.
2.5. React and JavaScript development community
Both development communities are vibrant and include a large number of developers. This community provides documentation, resources, and development support. By using both React and JavaScript, you can benefit from this vibrant development community.
2.6. Performance optimization
React uses Virtual DOM to optimize performance. Instead of updating the entire DOM, React only updates elements that have changed. This reduces processing time and improves application performance.
2.7. Cross-platform development
By combining React and JavaScript, you can develop web applications on various platforms. You can use React to develop web applications, mobile applications (using React Native), and desktop applications (using Electron). This can save you time and effort.
3. Summary
The combination of React and JavaScript allows you to get the best of both worlds when developing web applications. With state management, API integration, event handling and user interaction, component reuse, community support, and more, React JavaScript forms a powerful and flexible combination for launching modern web applications.
