The rise of WebAssembly (Wasm) has sparked debates about Java's future in a world where near-native web performance is possible without the JVM.WebAssembly challenges Java with its near-native speed in browsers, polyglot flexibility, and server-side disruption.Java could adapt through GraalVM's Wasm integration, Kotlin/Wasm experimentation, or the possibility of a WASI-enabled JVM.In a performance showdown, Wasm wins on startup time, but Java still dominates in long-running processes.Java might still thrive in enterprise applications, Android development, and big data, while potentially embracing Wasm for frontend modules.
