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.

sortedIndex
Returns the lowest index at which value should be inserted into array in order to maintain its sort order.
Check if the array is sorted in descending order (loosely). Use Array.findIndex() to find the appropriate index where the element should be inserted.

+  const isDescending = arr[0] > arr[arr.length - 1];
+  const index = arr.findIndex(el => (isDescending ? n >= el : n <= el));
+  return index === -1 ? arr.length : index;
