How Can I Use `Array.map` and `async/await` Together to Process Promises Correctly?

Array.map and Async/Await: Resolving Promise Compatibility

While the code snippet below aims to utilize Array.map and async/await, it triggers an error:

var arr = [1,2,3,4,5];

var results: number[] = await arr.map(async (item): Promise<number> => {
        await callAsynchronousOperation(item);
        return item + 1;
    });

The error stemmed from attempting to await an array of promises rather than a single Promise. The quick solution, however, lies in employing Promise.all to transform the promise array into a solitary Promise before awaiting its resolution.

var arr = [1, 2, 3, 4, 5];

var results: number[] = await Promise.all(arr.map(async (item): Promise<number> => {
    await callAsynchronousOperation(item);
    return item + 1;
}));
