JPG file

Greet, Vorn Guys I am a total beginner when it comes to computer coding so please do not mind about my question if it doesn’t make sense and please help me correct my mistake rather than straight up criticisming. Hopefully you understand my piont and let’s get into it. I wonder what computer language is used to make JPG file? If anyone know about that please share me your knowledge and please provide some of extra minor info that is related. Thank you
