Go 1.24 enhances its WebAssembly capabilities by introducing the go:wasmexport directive, allowing developers to export Go functions to Wasm for better integration with Wasm hosts. The addition of the ability to build a WebAssembly System Interface (WASI) reactor enables continuous operation of WebAssembly modules, expanding the possibilities for Go-based Wasm applications. Despite these advancements, limitations persist, such as the lack of parallelism in Wasm and restrictions on types used with go:wasmimport and go:wasmexport functions. Overall, Go 1.24 marks a significant advancement in empowering developers to create versatile and powerful Go-based Wasm applications.
