Converting my python script to Javascript

I wrote a python script that given a JSON and a list of .npy files, reads each file and prints the numpy arrays. I like to convert it into Javascript but all my attempts so far fails. What is the proper way to convert it?

Here is my Python script:

import numpy as np
import json

with open('model_weights.json', 'r') as f:
    json_data = json.load(f)

for layer_name, layer_data in json_data.items():
    print(f"Layer: {layer_name}")

    weight_file = layer_data['weight']
    weight_data = np.load(weight_file)
    print("Weight:")
    print(weight_data)

    # Read and print the bias data
    bias_file = layer_data['bias']
    bias_data = np.load(bias_file)
    print("Bias:")
    print(bias_data)

    print()

Which prints like this:

Layer: conv_mid.0
Weight:
[[[[ 5.11894599e-02  6.01319224e-02  2.16415059e-02]
   [-5.73022485e-01  6.34898171e-02 -5.68771400e-02]
   [-4.38963100e-02 -9.82442126e-02  2.19287891e-02]]
...
...
Bias:
[-0.00059052  0.00416504 -0.00031364  0.00533698 -0.01785151 -0.00343998
  0.00104868  0.00327141]
...
...

Here is the JSON:

{
    "conv_mid.0": {
        "weight": "conv_mid.0_weight.npy",
        "bias": "conv_mid.0_bias.npy"
    },
    "conv_mid.1": {
        "weight": "conv_mid.1_weight.npy",
        "bias": "conv_mid.1_bias.npy"
    },
    "conv_mid.2": {
        "weight": "conv_mid.2_weight.npy",
        "bias": "conv_mid.2_bias.npy"
    },
    "conv_mid.3": {
        "weight": "conv_mid.3_weight.npy",
        "bias": "conv_mid.3_bias.npy"
    }
}
