```

### Temporary build command with O2 level optimization

```shell

emcc  main.cpp h_test.cpp -O2 -o main.js -s WASM=1 -s ALLOW_MEMORY_GROWTH=1 -s FORCE_FILESYSTEM=1 -s TOTAL_MEMORY=268435456 -s EXPORTED_FUNCTIONS='["_malloc"]' -s EXTRA_EXPORTED_RUNTIME_METHODS='["cwrap"]'

```

### Commands

```shell

#Here _fib is the exported function.

emcc main.cpp -o main.js -s WASM=1 -s EXPORTED_FUNCTIONS='["_fib"]' -s EXTRA_EXPORTED_RUNTIME_METHODS='["cwrap"]'

```

```shell
