Overview of using the Web Workers Web API to move heavy JSON processing off the browser main thread. Covers a real-world use case (“Rinha Front end” in Brazil) where large JSON files were processed entirely client-side without blocking the UI, and demonstrates building a simple vanilla JavaScript app that creates and uses Web Workers to handle work outside the main thread.
