Travelers is just a demo site made on React js.
ReactJS is a popular open-source JavaScript library used for building user interfaces (UIs) and creating interactive front-end web applications. It was developed and is maintained by Facebook and a community of individual developers. React is known for its efficiency, reusability, and flexibility, making it a preferred choice for single-page applications (SPAs) and complex UI components.
Key features of ReactJS:
- Component-Based Architecture: React follows a component-based approach, where the UI is broken down into small, reusable components. Each component manages its own state and behavior, making it easier to build and maintain large applications.
- Virtual DOM: React uses a virtual representation of the actual DOM (Document Object Model) to optimize rendering performance. When there are changes to the UI, React updates the virtual DOM first, then efficiently determines the minimal changes required to update the actual DOM, leading to faster rendering.
- Declarative Syntax: React uses a declarative syntax, meaning developers describe what the UI should look like based on the application’s state, and React takes care of updating the actual DOM to match that state.
- JSX (JavaScript XML): React allows developers to write HTML-like code called JSX, which enables a more intuitive and seamless integration of HTML and JavaScript. JSX is later transpiled into regular JavaScript using tools like Babel.
- One-Way Data Binding: React follows a one-way data flow, meaning data flows in a single direction from the parent component to its children. This helps to maintain data consistency and avoid unexpected side effects.
