Javascript:From array of characters construct object

 

From array of characters, constructs an

object with index as key and character as value.

Code:

const arr =["a", "b", "c", "d", "e", "f"];

let result = arr.reduce((acc, curr, index) => {

   acc[index] = curr.toString();

   return acc;

}, {});

console.log(JSON.stringify(result, null, 2));

Output:

{

  "0": "a",

  "1": "b",

  "2": "c",

  "3": "d",

  "4": "e",

  "5": "f"

}

Explanation:

1. The code defines an array `arr` containing a series of strings.

2. It uses the `reduce` method to iterate over the array and construct an object.

3. For each element in the array, it adds a new property to the accumulator object `acc`,

using the index of the element as the key and the string value as the value.

4. Finally, it logs the resulting object as a JSON string with indentation for readability.
