Answer 1

What about use delete keyword?

delete personList[personId];

Answer 2

Since you're already assigning the keys of your object to the personId you can just do:

const Delete = (id: string): void => {
    const filteredPersonList: Record<string,PersonInfo> = {}
    for(let key in personList){
        if(key !== id){
            filteredPersonList[key] = personList[key]
        }
    }
    setPersonList(filteredPersonList)
}
