This document discusses parallel computing techniques in JavaScript including web workers, Node.js clustering, and asynchronous programming. It introduces parallel computing concepts and explains how JavaScript handles parallelism through an event loop, message queue, and asynchronous functions despite being a single-threaded language. Code examples are provided to demonstrate parallel computing approaches in JavaScript.
