Accessing the value from a Promise using await in JavaScript (day-18/18_Day_Promises.md)

We want to access the value returned from an asynchronous function using await, but it causes an error when used at the top level.

const square = async function (n) {
  return n * n;
}

const value = await square(2); // ❌await is only valid in async functions and the top level bodies of modules
console.log(value);

CORRECT APPROACH:

const square = async function (n) {
  return n * n;
}

async function main() {
  const value = await square(2);
  console.log(value); //  4
}

main();
