The internet has evolved dramatically since its inception, transforming from static pages into a dynamic, interactive, and highly sophisticated platform. With this evolution comes an ever-increasing demand for faster, more powerful, and more complex web applications. While JavaScript has long been the undisputed king of browser-side scripting, its single-threaded nature and interpretive execution sometimes hit performance ceilings when dealing with computationally intensive tasks. Enter WebAssembly (Wasm) – a groundbreaking technology designed to elevate web performance to unprecedented levels, allowing developers to run high-performance code directly in the browser.

In the intricate world of software development, ensuring the quality and reliability of a product is paramount. Software testing plays a pivotal role in achieving this, acting as a critical gatekeeper before a product reaches its end-users. Within the broad spectrum of software testing, two fundamental categories stand out: Functional Testing and Non-Functional Testing. While both are indispensable for delivering a robust and user-friendly application, they address different aspects of software quality. Understanding their distinctions, purposes, and interdependencies is crucial for any development team aiming for excellence.
