set array values as object key using javascript or jquery [duplicate]

Question

I have an array like

array(
  [0] => value1
  [1] => value2
  [3] => value3
   .
   .
  [n] => valuen
)

I want this array values as object key like

object{"value1":{"value2":{"value3":"..."}}}

How can I achieve this.

Thanks in advance

What will the value be of the inner-most property in the result? The last value from the array? Anyway, the .reduce() method or a simple loop will do the trick. — nnnnnn

Use Array.reduce

const result = arr.reverse().reduce((acc, cur) => ({[cur]: acc}), {});

Example:

const result = ['a', 'b', 'c', 'd'].reverse().reduce(
  (acc, cur) => ({[cur]: acc}), {});

console.log(result); // {a: {b: {c: {d: {}}}}}
