How to flatten object of objects recursively into array

Question

I have an object like this:

const myObj = {
  a: {
    b: {
      c: 1,
      d: 2
    },
    f: {
      z: 4,
      u: 6
    }
  }
}

into this:

const myObj = [
  {
    c: 1,
    d: 2,
  },
  {
    z: 4,
    u: 6,
  }
]

I found this: How to recursively transform an array of nested objects into array of flat objects? but the original is an array of objects, and mine is an object itself.

What is the exact criteria for flattening?

You can traverse the values of the objects until you reach the leaves (objects with no values that are other objects).

const myObj = {
  a: {
    b: {
      c: 1,
      d: 2
    },
    f: {
      z: 4,
      u: 6
    }
  }
};
const flatObj = o => Object.values(o).some(x => x === Object(x)) ?
  Object.values(o).flatMap(flatObj) : [o];
console.log(flatObj(myObj))
