You can use the async keyword to create an asynchronous function, which returns a promise.

Example Code
const example = async () => {
  console.log("this is an example");
};

The try block is designed to handle potential errors, and the code inside the catch block will be executed in case an error occurs.

Example Code
try {
  const name = "freeCodeCamp";
  name = "fCC";
} catch (err) {
  console.log(err); // TypeError: Assignment to constant variable.
}

The await keyword waits for a promise to resolve and returns the result.

Example Code
const example = async () => {
  const data = await fetch("https://example.com/api");
  console.log(data);
}
