I have this code
let array = []; const datas = [ 'name1', 'name2', 'name3', ]; async function getData() { datas.forEach((data) => { let myData = data.name; if(!array.includes(myData)){ array.push(myData); } }) let result = await array; console.log('Result', result); }; getData();
that returns an array that contains strings like
['name1','name2', 'name3']
And I would like to make all of the array
indexes arrays themselves, so I can later push data in the array’s indexes, like
['name1': [], 'name2': [], 'name3': []]
Does somebody know how to do this in plain javascript ?

If i understood well, seems you need something like this
let obj = {}; const datas = [ 'name1', 'name2', 'name3', ]; function getData() { datas.forEach((data) => { obj[data] = [] }) console.log('Result', obj); }; getData();
Result { name1: [], name2: [], name3: [] }
tip: Array keys can be only indexes
