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();
