We can add a return if isAllUnique = false instead to make the program run more efficiently

You may want to consider exiting loop if isAllUnique==false. Otherwise, it will loop through the whole array.

If you add a return as soon as you find a duplicate, it will be more efficient because it won't have to keep searching through the rest of the array

Consider limiting the number of loops within loops to improve time efficiency

Add a comment to describe what type of uniqueness you are looking for (unique characters? unique array items?)

I feel like we should be returning isAllUnique right away if it is false so that the code doesn't have to continue through the entire array before returning.

Could we rename to areAllElementsUnique? Might read a little more smoothly ...

Returns true for empty array -- should it return null instead?

Can we refactor to exit the loop as soon as it is false?

good function to check for unique elements
