How to convert an array of string to an Object

 There are couple of ways to achieve this. 

Method one is to use Object.Assign().

More information can be found here

Eg:

let arr = ["apple", "strawberry", "banana", "cherry", "tomato", "carrot", "plum"];

let x = Object.assign({}, arr);

//{

//     '0': 'apple',

//     '1': 'strawberry',

//     '2': 'banana',

//     '3': 'cherry',

//     '4': 'tomato',

//     '5': 'carrot',

//     '6': 'plum'

//   }

Method two is to use Object.fromEntries().
What it does is it transforms a list of key/value pairs in to an object. More information can be found here.

Eg:

let keyValueList = [

  ["1x", "apple"],

  ["2x", "strawberry"],

  ["3x", "banana"],

  ["4x", "cherry"],

  [5, "tomato"],

];

let x = Object.fromEntries(keyValueList);

console.log(x);

// {

//     '5': 'tomato',

//     '1x': 'apple',

//     '2x': 'strawberry',

//     '3x': 'banana',

//     '4x': 'cherry'

//   }

Method two is to use Array.map().

This method creates a new array populated with the results of calling a provided function on every element in the calling array. more information can be found here.

let arr = ["apple", "strawberry", "banana", "cherry", "tomato", "carrot", "plum"];

let y = {};

let x = arr.map((item, index) => {  // arr.forEach can also be used here

  return (y[index] = item);

});

console.log(y);

// {

//     '0': 'apple',

//     '1': 'strawberry',

//     '2': 'banana',

//     '3': 'cherry',

//     '4': 'tomato',

//     '5': 'carrot',

//     '6': 'plum'

//   }

There could be more ways to do this as well such a using a for loop and so on.
