blank? will load the entire array, then check to see if the array is empty.

On the other hand, empty? asks the database for a count, and checks to see if that count is zero or not. This might not make a difference in small datasets (like development), but it can make a big difference in databases with large datasets (like production).

It will also make a huge difference in memory consumption when thousands of records are loaded vs a single integer.

map will load the entire array, then iterate to collect the screen_names.

pluck asks the database for exactly what it needs and returns an array of just those items.

So in case of pluck, performance is gained and less memory is used for large datasets (like production).

Never use map on active record relations, use pluck instead.

If you're using pluck to pass values to a where use select instead
