If enabled, targets the WebAssembly.Table
language feature, which results in faster JS-Wasm interop and faster build times. WebAssembly.Table
is not backwards compatible with the older dynCalls
interop model. If disabled, Unity targets the old deprecated Emscripten -sDYNCALLS
flag for backwards compatibility with older Unity Web platform JS plugin code. It is recommended to enable this option for new projects that do not utilize any older incompatible JavaScript plugins, and when fast you prefer build iteration times, and to disable it if utilizing .jslib
files that rely on the older dynCall()
mechanism.
