🤔 Optimization:

▶️ Pre-allocate Memory: By creating a new array with new Array(arr.length), we allocate the required memory upfront, which can be more efficient for large arrays.

const newArray = new Array(arr.length);

▶️ Direct Assignment: Assigning the transformed value directly to the array index avoids the overhead of the push operation.

newArray[i] = fn(arr[i], i);

👉 "Promise.all" takes an array of promises and returns a single promise that resolves when all of the promises in the array have resolved. The resolved value will be an array of the resolved values of the input promises.

👉 The "then" method is used to handle the resolved values of the promises. It takes a callback function that receives the resolved values as an array.
