Accumulate

For example, given the collection of numbers:

• 1, 2, 3, 4, 5

And the operation:

• square a number

Your code should be able to produce the collection of squares:

• 1, 4, 9, 16, 25

Optional Extras

• Square Root a Number

• Cube a number

• Even and Odd

• Or return an object containing all of those things:

  {
    original: [1, 2, 3, 4, 5],
    squares: [...],
    squareRoots: [...],
    cubes: [...],
    evenAndOdd: [true, false, true]
  }
  

Restrictions

Keep your hands off that collect/map/fmap/whatchamacallit functionality provided by your standard library!

Solve this one yourself using other basic tools instead.
