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?user6749601– user67496012021-04-09 01:12:24 +00:00Commented Apr 9, 2021 at 1:12

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]])
}

actually i want to do this myObj[arr[0]][arr[1]][arr[2]] join will make it something like myObj[this is my test] i want myObj['this']['is']['my']['test']
arrickx
then you could do
var Obj = [[arr[0]],[arr[1]],[arr[2]]];user3858744
