Convert array to object keys

What's the best way to convert an array, to an object with those array values as keys, empty strings serve as the values of the new object.

['a','b','c']

to:

{
  a: '',
  b: '',
  c: ''
}

try with Array#Reduce

const arr = ['a','b','c'];
const res = arr.reduce((acc,curr)=> (acc[curr]='',acc),{});
console.log(res)

You can use https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce">`Array.prototype.reduce()`</a>and https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer#Computed_property_names">Computed property names

let arr = ['a','b','c'];
let obj = arr.reduce((ac,a) => ({...ac,[a]:''}),{});
console.log(obj);

var target = {}; ['a','b','c'].forEach(key => target[key] = "");

You can use Object.assign property to combine objects created with a map function, please take into account that if values of array elements are not unique the latter ones will overwrite previous ones

const array = Object.assign({},...["a","b","c"].map(key => ({[key]: ""})));
console.log(array);

You can use array reduce function & pass an empty object in the accumulator. In this accumulator add key which is denoted by curr

let k = ['a', 'b', 'c']

let obj = k.reduce(function(acc, curr) {
  acc[curr] = '';
  return acc;
}, {});
console.log(obj)
