This paper explores the application of JavaScript development frameworks React and Redux in web applications that utilize CRUD (Create, Read, Update, Delete) operations. Focusing on the React technology, this paper examines how these tools collectively contribute to the development of modern web applications. React is a popular JavaScript library that enables the creation of dynamic and responsive user interfaces, while Redux is a powerful state management tool for applications. Bootstrap, with its CSS component library, makes designing user interfaces quick and straightforward. The first part of the paper introduces us to understanding CRUD operations, then provides a detailed description of React and Redux, along with their advantages and disadvantages. Bootstrap is used to create appealing user interfaces. This research demonstrates that the use of React, Redux, and Bootstrap in combination provides a robust toolkit for web application development. Their advantages outweigh the drawbacks, allowing developers to rapidly create high-quality web applications that are functional and appealing to users. This technology combination remains crucial for the development of modern web applications in today's digital environment.
