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