Jack Harlow is a popular young white rapper who flexes a certain precision and who sometimes raps fast. As such, he was always going to have to engage with Eminem on some level, even though he really sounds nothing like Em (and even though he was less than a year old when The Slim Shady LP came out). Harlow had two choices: He could either jump on a track with Eminem, or he could beef with him. He jumped on a track with Eminem.
