[removed] Whats the best way Convert Array into Object? [duplicate]

Answer 1

Use Array#reduce method to reduce into a single object.

a = ['USD', 'EUR', 'INR'];

console.log(
  a.reduce(function(obj, v) {
    obj[v] = 0;
    return obj;
  }, {})
)

Or even simple for loop is fine.

var a = ['USD', 'EUR', 'INR'];
var res = {};

for (var i = 0; i < a.length; i++)
  res[a[i]] = 0;

console.log(res);
