I have an array of type:-
const arr = ['abc','def','ghi'];
but I want this array in the form of
const arr2 = [
{value: 'abc'},
{value: 'def'},
{value: 'ghi'},
];
I am not getting the idea to do it.

Voting to reopen since this question is clear and focused, but perhaps I'm missing something. Would those who chose to close this because it "needs to be more focused" care to explain?skomisa– skomisa2020-04-17 20:41:52 +00:00Commented Apr 17, 2020 at 20:41

use a map function to generate a new array with the type you want
for your reference, Array.prototype.map()
const arr=['abc','def','ghi'];
const arr2 = arr.map(item => ({value: item}));
console.log(arr2);

You can try using Array.prototype.map():
The
map()method creates a new array populated with the results of calling a provided function on every element in the calling array.
var arr = ['abc','def','ghi'];
arr = arr.map(value => ({value}));
console.log(arr);

You can use map to transform each item of an array to another value.
const arr = ['abc', 'def', 'ghi'];
const arr2 = arr.map(value => ({ value: value })
// const arr2 = [
// { value: "abc" },
// { value: "def" },
// { value: "ghi" }
// ];
If you want to be clever you can simplify this to
const arr2 = arr.map(value => ({ value })
See Array.prototype.map

More elegant way that I prefer:
Array.from(arr, (v) => {return {value: v};})
