How do I convert this to a functional component?

I’m trying to practice reactjs and how can I convert this class component to a functional component?

     handleChange = (e) => {
    const { name, value } = e.target;
    this.setState( {
        [name] :value
    })
  };

So far, I could only do this and I’m quite lost when it comes to the this.setState

 const handleChange = (e) => {
    const { name, value } = e.target;
  };
