[ключ, значение] методом fromEntries():Object.fromEntries(arr.map((v, i) => [i + 1, v]))map() создаётся новый, где каждый элемент это тоже массив:[ [1, 'a'], [2, 'b'], ... ]Object.fromEntries() для получения искомого объекта.
Мое решение:
let arr = ['a', 'b', 'c', 'd', 'e'];
let obj = {};
for (let i = 0; i <= arr.length; i++) {
obj[i + 1] += arr;
}
console.log(obj);+= ? Вы же не плюсуете к чему то, а назначаете значение. То есть - obj[i + 1] += arr;
+ obj[i + 1] = arr;- obj[i + 1] = arr;
+ obj[i + 1] = arr[i];let arr = ['a', 'b', 'c', 'd', 'e'];
let obj = {};
for (let i = 1; i <= arr.length; i++) {
obj[i] = arr[i-1];
}
console.log(obj);let arr = ['a', 'b', 'c', 'd', 'e'];
let obj = arr.reduce((a, c, i) => (a[i+1] = c, a), {});
console.log(obj);
