Given a key and a set of arguments, call them when given a context. Primarily useful in composition.

Use a closure to call a stored key with stored arguments.

howManyTimes
Returns the number of times num can be divided by divisor (integer or fractional) without getting a fractional answer. Works for both negative and positive integers.
If divisor is -1 or 1 return Infinity. If divisor is -0 or 0 return 0. Otherwise, keep dividing num with divisor and incrementing i, while the result is an integer. Return the number of times the loop was executed, i.
const howManyTimes = (num, divisor) => {
+  if (divisor === 1 || divisor === -1) return Infinity;
+  if (divisor === 0) return 0;
+  let i = 0;
+  while (Number.isInteger(num / divisor)) {
+    i++;
+    num = num / divisor;
+  }
+  return i;
+};
