Web workers, React, and TypeScript

Web workers are a browser feature that allows running JavaScript processes in the background, enhancing web application performance by offloading long-running tasks from the main thread. This capability is particularly useful in scenarios where heavy computations could otherwise block the UI, impacting user experience. In a project setup involving React and TypeScript, web workers can be effectively utilized to manage operations such as handling large datasets and implementing pagination. By using multi-threading through web workers, developers can ensure that tasks like filtering, slicing, and mapping over large arrays are processed without affecting the main thread's performance. The text also outlines the implementation of web workers for a paginated data table, including the setup of a React project, creation of TypeScript data types and enums, and the design of a loader component to indicate processing status. Additionally, it discusses how to employ TypeScript for defining types and creating web workers for data retrieval and pagination, ultimately improving the user experience by allowing the main thread to remain responsive while handling background processes efficiently.
