cwrap() can also do some simple type conversions, for JS strings to C strings and JS arrays to C arrays, see
https://kripken.github.io/emscripten-site/docs/api_reference/preamble.js.html#cwrap Just calling the function directly means that you use types available in asm.js and wasm, which are just integers and floats, and no special support for strings or arrays (for example a C string is just a pointer, which is just an integer).
