I need to implement same python code in node js
The input value of byte is AES key generated by Kyber encryption algorithm
import base64
byte= b'\xa1\xd9\xde\xb0\xed\xbfo\xbdKcW\xdf\xafw\xdf\xb3\xe5\xe0j\x91\xb0t\xed\xb2\xf0\x01\x196\xf1\xd4\xe0\xc0'
base64_byte_array = base64.b64encode(byte)
base64_byte_array_string = base64_byte_array.decode()
print(base64_byte_array_string)
### odnesO2/b71LY1ffr3ffs+XgapGwdO2y8AEZNvHU4MA=
b64_string_bytes = base64_byte_array_string.encode()
byte_array = base64.b64decode(b64_string_bytes)
print(byte_array)
