Why let declared once?

Hi! Why let declared once? let stevenJ = { name: 'Steven', age: 22 }, sarah = { name: 'Sarah', age: 23 }, stevenS = { name: 'Steven', age: 22 };

instead of

let stevenJ = { name: 'Steven', age: 22 };

let sarah = { name: 'Sarah', age: 23 };

let stevenS = { name: 'Steven', age: 22 };
