Parallel execution allows multiple asynchronous operations to run simultaneously rather than sequentially. This significantly reduces total waiting time when tasks are independent of each other.
Yes, asynchronous programming concepts including promise handling and parallel execution are commonly discussed in modern frontend and JavaScript interviews. Companies often test understanding of concurrency patterns and promise utilities.
An array is typically used to store the promises and their resulting values. Arrays maintain ordering, making it easy to match each result to its original asynchronous task.
The optimal approach is to start all asynchronous tasks simultaneously and store their returned promises. Using utilities such as Promise.all allows all promises to resolve in parallel while preserving the order of results.
