Cached Astronomy Picture of the Day

This flow will download the latest Astronomy Picture of the Day (APOD) from and caches in memory.

It hits the API once every 24 hours, so you don't have to worry about reaching your quota.

Calls to the API will read from the cached version.

NOTE: to use this flow you must obtain a free API key from

// loop through the string, starting at the end.
for (var i = stringToReverse.length; i > 0; i--) {
// push the character at the current index into the finalString array
// Join the characters in the array into a string and return the string.
