Nodejs code to convert hex string to byte array?

Question

Can anyone please tell me equivalent Nodejs code to convert hex string to byte array which is in Java

public static byte[] hexStringToByteArray(String s) {
    byte[] b = new byte[s.length() / 2];
    for (int i = 0; i < b.length; i++) {
        int index = i * 2;
        int v = Integer.parseInt(s.substring(index, index + 2), 16);
        b[i] = (byte) v;

    }
    return b;
}

You can use Buffer.from(str, [encoding]) to perform the conversion.

Buffer.from(str, 'hex');
