Async IIFE vs. Thenable

Question

Immediately-Invoked Function Expression:

(async (myVal) => {
  try {
    // stuff
  } catch (err) {
    console.log(err);
  }
})(myVal)

Thenable:

Promise.resolve()
  .then(async (myVal) => {
    // stuff
  })
  .catch((err) => {
    console.log(err);
  });

The self-invoked runs quicker. Other than that, any specific advantage to utilize one over the other and in which situations?

Answer 1

Some other differences:

• It looks nicer
• It uses myVal instead of undefined for the local myVal variable
• It's syntax and doesn't rely on the global value of Promise or its methods
