Partially Hidden String

Create a function that takes a phrase and transforms each word using the following rules:

1. Keep first and last character the same.
2. Transform middle characters into a dash -.

Examples

partiallyHide("skies were pretty") ➞ "s---s w--e p----y"

partiallyHide("red is not my color") ➞ "r-d is n-t my c---r"

partiallyHide("She rolled her eyes") ➞ "S-e r----d h-r e--s"

partiallyHide("Harry went to fight the basilisk") ➞ "H---y w--t to f---t t-e b------k"

Notes

Words with two or fewer letters should not be hidden at all.
