Convert Date Format

Can someone please help me with the Target Code (executeScript_Sandbox) for converting the following copied date format as seen below:

Mon-DD-YYYY = Month abbreviation, Day with leading zeros, Year (Feb 17, 2021)

Then convert it to the following format:

MM/DD/YY = Month-Day-Year with leading zeros (02/17/2021)

Your help is greatly appreciated I did find the following links as reference points, however, they did not help obtain the results I am looking for:
