How to pass a pointer to float array in Javascript

I have the following C function that takes in an array compressed by the zfp library, and attempts to decompress it.

```
int EMSCRIPTEN_KEEPALIVE zfpDecompress(int precision, float* array, int nx, int ny,int nz, unsigned char* buffer, int compressedSize) {
int status = 0; /* return value: 0 = success */
zfp_type type; /* array scalar type */
zfp_field *field; /* array meta data */
zfp_stream *zfp; /* compressed stream */
bitstream *stream; /* bit stream to write to or read from */

type = zfp_type_float;
field = zfp_field_3d(array, type, nx, ny, nz);
zfp = zfp_stream_open(NULL);

zfp_stream_set_precision(zfp, precision);
bufsize = zfp_stream_maximum_size(zfp, field);

stream = stream_open(buffer, bufsize);
zfp_stream_set_bit_stream(zfp, stream);
zfp_stream_rewind(zfp);

if (!zfp_decompress(zfp, field))
{
status = 1;
}

zfp_field_free(field);
zfp_stream_close(zfp);
stream_close(stream);

return status;
}
```

I am attempting to call this function in Typescript (a React client), by passing it the compressed array received by the client. I have the communication set up correctly, since I can call more basic functions without a problem.

I am trying something like this:

```
floatArray = new Float32Array(size)
floatArray = response.getFloats() // set array to some float32Array

ZFP.zfpDecompress(0.01, floatArray, dimensionX, dimensionY, dimensionZ, buffer, bufferSize)
```

However, it returns 1, meaning the decompression was not successful. I suspect that I am not passing in the array correctly. What is the correct way to pass in a pointer to an array in Javascript / Typecript using Emscripten?
