async await forEach

Comment

// Array.prototype.forEach is not designed for asynchronous code.
// Instead use await Promise.all to process all in parallel if the order doesn't matter.
await Promise.all(array.map(async (element) => {
  await someFunction(element);
}))

js await in foreach

Comment

// Javascript will proceed to call the code that comes AFTER the forEach loop, 
// and then execute the code within the loop. This is because forEach is not 
// async-aware. YOU CANNOT USE AWAIT IN FOREACH. Use a regular for loop instead.
