React is a cross-platform library created by Jordan Walke, a JavaScript developer. It has been used in the development of websites, web applications, games, and mobile apps. Since the library is free, it is possible to use it without coding knowledge. However, the language is not suitable for beginners. It can be a little difficult to learn, and it may take some time to get used to it. Fortunately, there is extensive documentation on the Internet that can guide you through the process.
React is based on the idea of single elements that are combined to form larger elements. Each single element displays certain information, reacts to user input, and then gets rewritten based on that input. React has several lifecycle methods, including shouldComponentUpdate, which prevents a component from re-rendering. Another important lifecycle method is componentDidMount, which calls render when the component has mounted. This is usually used to trigger data loading from a remote source. The last lifecycle method is render. This method is called whenever a component’s state changes. It should update the user interface accordingly.
React is the most commonly used component-based framework, and it supports HTML and CSS. It uses a simple syntax, JSX, that allows HTML to be mixed with JavaScript (click here). Despite its ease of use, the biggest disadvantage of React is the fact that there is no documentation for it, and the community is very young. Hence, there is not enough information about the language, but it is a great place to start if you’re unsure.
