Just want to point out that the browser, and electron, and even node.js are multithreaded... it&#x27;s only the JS engine itself that is a single thread.  Asynchronous code and the UI engine itself definitely runs and interacts across threads.  Also, there&#x27;s also WebWorkers (while not great, can work in some cases).<p>There are also native modules for Electron&#x2F;Node which can work in background processes.<p>In the end, for the most part, in most applications, there isn&#x27;t much logic that actually takes advantage of multiple concurrent threads for logic, and I&#x2F;O is already multi-threaded.
