In the past few chapters, we have focused on Node.js and how we can write backend applications utilizing the same language as the frontend. We have seen various ways of creating servers, offloading tasks, and streaming. In this part, we will focus on the offloading tasks aspect of the browser.
Eventually, as we have seen in Node.js, we need to offload some computationally intensive tasks from the main thread to a separate thread, or process, to make sure that our application stays responsive.
