Summary

This tutorial explores the use of web workers in a React application to enhance responsiveness and performance by offloading heavy computations to the background. It explains how web workers can prevent a webpage from becoming unresponsive during resource loading and introduces the useWorkerizedReducer, a variation of the useReducer Hook, which allows state updates to be processed in a web worker. The guide walks through the process of setting up a simple counter application using useWorkerizedReducer, detailing how to create and incorporate a worker.js module and integrate it with the main application. By placing reducers in web workers, developers can maintain application responsiveness even with long-running computations. The tutorial also highlights the importance of asynchronous operations in reducers and the communication between the main thread and the worker through postMessage() for state synchronization.
