Get value of child object’s using a variable referencing that key

I have below object and I can reference key e as in the following:

var obj = {
"id": 100,
"date": "2021",
"d": "D",
"e": {
    "e1": "E"
"f": {
    "f1": "F"

console.log(obj.e); // returning { e1: 'E' }

I want to get the value by using the object key as below and input [Key] always be a that place.

"d": "D",
"e": "E",
"f": "HardCode FF"

How can I do this?
