What is the advantage of the syntactic sugar represented by async/await compared to Promise?

The main advantage of async/await over "plain" promises is the ability to write asynchronous code in a more synchronous and readable style.

Comparison:

Aspect	Promise	async/await
Readability	Can lead to "promise chains".	Allows writing code almost like synchronous.
Error handling	Uses .catch().	Uses standard try...catch.
Sequence	Requires careful chaining or Promise.all.	Explicit and easy to read.
Debugging	Can be harder to follow the flow.	Closer to debugging synchronous code.
Syntactic noise	Lots of .then(), .catch().	Less boilerplate code.

Example with promises:

// Promise example
fetch('user.json')
  .then(response => response.json())
  .then(user => fetch(`https://api.github.com/users/${user.name}`))
  .then(githubUser => githubUser.json())
  .then(githubUser => {
    // Data processing
    console.log(githubUser);
  })
  .catch(error => {
    console.error('Error:', error);
  });

Example with async/await:

// async/await example
async function getUserData() {
  try {
    const userResponse = await fetch('user.json');
    const user = await userResponse.json();

    const githubResponse = await fetch(`https://api.github.com/users/${user.name}`);
    const githubUser = await githubResponse.json();

    // Data processing
    console.log(githubUser);
  } catch (error) {
    console.error('Error:', error);
  }
}

getUserData();

Thus, async/await does not replace promises but is syntactic sugar over them, making asynchronous operations more intuitive and easier to maintain.
