If I have an array:

const arr = ['this', 'is', 'my', 'test'];

How can I dynamically do

myObj[arr[0]][arr[1]][arr[2]]

  • it is not clear what you want. Do you want to map an array field by field into an object? –  Apr 09 '21 at 01:12
  • @Lynx242 i need to do this programmatically myObj['this']['is']['my']['test'] – user3858744 Apr 09 '21 at 01:37

I am not sure if this is what you are looking for? enter link description here

const arr = ['this', 'is', 'my', 'test'];
var Obj = arr.join(" ");
console.log(Obj)

--------------------------------please see this as updated ---------------------

const arr = ['this', 'is', 'my', 'test'];

var Obj = [];
var i;
for (i = 0; i < arr.length; i++) {
  Obj.push([arr[i]])
}
