What native mechanism in JavaScript allows implementing sequential scenarios with response waiting (e.g., onboarding or multi-step forms)?

In JavaScript, the mechanism of async/await is used to implement sequential scenarios that wait for a response, such as multi-step forms or onboarding.

It is syntactic sugar over promises, allowing you to write asynchronous code that looks like synchronous code, making it easier to read and maintain.

Example:

async function onboarding() {
  const step1 = await completeStep1();
  const step2 = await completeStep2(step1);
  const step3 = await completeStep3(step2);
  console.log('Onboarding completed');
}

onboarding();

Here, each step waits for the previous one to finish, which is convenient for sequential operations with asynchronous calls.
