What's the difference between referencing and using a callback to invoke generateHTML?

I realize you can also just nest generateHTML inside an arrow function to work as a callback

btn.addEventListener("click", () => { getJSON(astroUrl, (json) => { json.people.map((person) => { getJSON(wikiUrl + person.name, (data) => { generateHTML(data); }); }); }); });

How is it different from simply referencing generateHTML?

btn.addEventListener("click", () => { getJSON(astroUrl, (json) => { json.people.map((person) => { getJSON(wikiUrl + person.name, generateHTML); }); }); });
