Garbage collection is an automatic memory management system used in programming languages like Java. It automatically identifies and frees up memory that is no longer being used by a program, preventing memory leaks that can cause slowdowns and crashes.

The WASM-GC engine relies on advanced browser extensions like JSPI (WebAssembly JavaScript Promise Integration).

The browser-based Minecraft gaming community has reached a massive milestone with the release of . Initially launched as an experimental project to port older versions of Minecraft Java Edition directly into a browser, Eaglercraft has evolved into a highly optimized gaming platform. By ditching traditional JavaScript execution for a modern WASM-GC runtime, developers have unlocked performance tiers that make the beloved World of Color update smooth and playable on nearly any web-connected machine.

It is important to note that WASM-GC is a cutting-edge technology, and as such, it has its own requirements. It requires a built on a recent engine that supports the WASM-GC specification, such as the latest versions of Google Chrome, Microsoft Edge, or Mozilla Firefox. For older devices or institutional computers with outdated browsers, the classic JavaScript version remains a reliable, albeit less performant, alternative.
