javascript create array of objects with key
You will be able to get the current iteration's index for the map method through its 2nd parameter.
Example:
const list = [ 'h', 'e', 'l', 'l', 'o'];
list.map((currElement, index) => {
console.log("The current iteration is: " + index);
console.log("The current element is: " + currElement);
console.log("\n");
return currElement; //equivalent to list[index]
});
