You can try with .forEach() as the following:
const arr = ["value1", "value2"];
const result = {};
arr.forEach(e => result[e] = {});
console.log(result);Comments
You could take Object.fromEntries and map the wanted keys with empty objects.
let keys = ["value1", "value2"],
object = Object.fromEntries(keys.map(key => [key, {}]));
console.log(object);

Use array reduce!
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduce
arr.reduce((accumulator, value) => ({ ...accumulator, [value]: {} }), {});

Or: ``` arr.reduce((accumulator, value) => Object.assign(({ [value]: {} }, accumulator)))```
You can use .reduce() to get the desired output:
const data = ["value1", "value2"];
const result = data.reduce((r, k) => (r[k] = {}, r), {});
console.log(result);

There's also Object.fromEntries method specifically designed to convert an array of entries (key-value tuples) to an Object.
let arr = ['value1', 'value2'];
let entries = arr.map(el => [el, {}]);
let obj = Object.fromEntries(entries);
console.log(obj);
