Is there a way for me to create an object where the key is the same and the values are set from an array.

I want the key = data and value to be set from an array.

key = data
arr = ['abc', 'pqr', 'xyz']

I need my object to be:

my_obj = [{data: 'abc'}, {data: 'pqr'}, {data: 'xyz'}]

I am not sure how to create such an object.

No, that wouldn't work. A key must be unique. Given your requirements, why could you not just use my_obj = { data: ['abc', 'pqr', 'xyz'] };? — fubar

No, JavaScript objects cannot have duplicate keys. The keys must all be unique. stackoverflow.com/questions/3996135/… — Twisty

Does this answer your question? JS associative object with duplicate names — Twisty

You can achieve that by using map(), something like:

let arr = ['abc', 'pqr', 'xyz']

let my_obj = arr.map(e => ({ data: e }))

console.log(my_obj[0].data) // 'abc'
console.log(my_obj[1].data) // 'pqr'
console.log(my_obj[2].data) // 'xyz

console.log(my_obj)

To use the string assigned to the key variable as the key of the object, you can use arr.map(e => ({ [key]: e })). See codeburst.io/…

I'm not sure we want a computed property name in this case, OP seems to want just data.

I saw "I want the key = data..." in the question and thought a computed property name was required.

Got it, I think the OP literally meant the object keys to be "data" :)
