Should I use fetch() with .then() or async/await? [duplicate]

The following pieces of code are giving me the same result. What is the difference between the use of .then() and async/await to fetch data?

// Code 1 function fetchData() { fetch(url) .then(response => response.json()) .then(json => console.log(json)) } // Code 2 async function fetchData() { const response = await fetch(url); const json = await response.json(); console.log(json); }
