Interface for dynamic key in typescript

Question

I have an Object like this that is created by underscore\'s _.groupBy() method.

myObject = {
  \"key\" : [{Object},{Object2},{Object3}],
  \"key         


        

Answer 1

don't know about interface, for dynamic objects we can go something like this:

let memoTable: { [k: number]: number } = {};
memoTable[1]=5;
memoTable[2]=7;
