Why JSX is not working ?

How to loop an array and based on this create a dynamic CTE but preserve type ?

      for (const [references, columns] of referencesArray) {
        const newQb = qb.with(`cte_${references}`, (wb) => {
          wb = wb.selectFrom(references).distinct().selectAll(references);
          for (const column of columns) {
            wb = wb.innerJoin(
              tableName,
              sql.ref(`${tableName}.${column.name}`),
              sql.ref(`${column.references}.${column.to}`)
            );
          }
          return wb;
        });
        qb = newQb as any;
      }

      for (const [references, columns] of referencesArray) {
        const newQb = qb.with(`cte_${references}`, (wb) => {
          wb = wb.selectFrom(references).distinct().selectAll(references);
          for (const column of columns) {
            wb = wb.innerJoin(
              tableName,
              sql.ref(`${tableName}.${column.name}`),
              sql.ref(`${column.references}.${column.to}`)
            );
          }
          return wb;
        });
        qb = newQb as any;
      }

But this is not optimal

Python alternative to ctypes, can't figure how to convert a code

Hello, I am trying to convert a Python ctypes code to Deno using FFI, but can't know why its not working

import ctypes

class WhisperFullParams(ctypes.Structure):
    _fields_ = [
        ("strategy", ctypes.c_int),
        #
        ("n_max_text_ctx", ctypes.c_int),
        ("n_threads", ctypes.c_int),
        ("offset_ms", ctypes.c_int),
        ("duration_ms", ctypes.c_int)

    whisper.whisper_init_from_file.restype = ctypes.c_void_p
    whisper.whisper_full_default_params.restype = WhisperFullParams
    whisper.whisper_full_get_segment_text.restype = ctypes.c_char_p

    # initialize whisper.cpp context
    ctx = whisper.whisper_init_from_file(fname_model.encode("utf-8"))

    # get default whisper parameters and adjust as needed
    params = whisper.whisper_full_default_params()
    params.print_realtime = True
    params.print_progress = False

    # load WAV file
    samplerate, data = wavfile.read(fname_wav)

    # convert to 32-bit float
    data = data.astype("float32") / 32768.0

    # run the inference
    result = whisper.whisper_full(
        ctypes.c_void_p(ctx),
        params,
        data.ctypes.data_as(ctypes.POINTER(ctypes.c_float)),
        len(data),
    )

import ctypes

class WhisperFullParams(ctypes.Structure):
    _fields_ = [
        ("strategy", ctypes.c_int),

        ("duration_ms", ctypes.c_int)

    whisper.whisper_init_from_file.restype = ctypes.c_void_p
    whisper.whisper_full_default_params.restype = WhisperFullParams
    whisper.whisper_full_get_segment_text.restype = ctypes.c_char_p

        params,
        data.ctypes.data_as(ctypes.POINTER(ctypes.c_float)),
        len(data),
    )

I am looking for a bit of help, any would be gladly welcomed ! For now the code just hang when calling whisper.whisper_full_default_params
