How to validate .jpe files in Python

Python
def is_jpe(file_path: str) -> bool:
    """Check if file is a valid JPE by magic bytes."""
    signature = bytes([0xFF, 0xD8, 0xFF])
    with open(file_path, "rb") as f:
        return f.read(3) == signature

How to validate .jpe files in Node.js

function isJPE(buffer: Buffer): boolean {
  const signature = Buffer.from([0xFF, 0xD8, 0xFF]);
  return buffer.subarray(0, 3).equals(signature);
}

How to validate .jpe files in Go

Go
func IsJPE(data []byte) bool {
    signature := []byte{0xFF, 0xD8, 0xFF}
    if len(data) < 3 {
        return false
    }
    return bytes.Equal(data[:3], signature)
