Choose V8 if you want authentic redstone and combat . Choose Javaify for lightweight visuals.

Several developers release "Java" style addons for MCPE, often sharing similar names or versioning numbers:

Java Edition runs on the JVM (Java Virtual Machine). Bedrock runs on a C++ core with a JavaScript layer for addons (powered by V8). The modern modding scene has developed "abstraction layers"—middleware that translates Java mod requests into V8 JavaScript commands.

The introduction of these conversion tools has fundamentally altered the Minecraft PE experience. Historically, mobile players had access only to simple add-ons available on the Minecraft Marketplace or community forums. These were often limited to simple item additions or slight mob behavior changes.
