# then use a range object to do 0 to 5 counts
# EC: It looks like elements.push(0..5) adds a value of "0..5" to the first element of the elements array, so you need to actually use a for loop to populate it, or maybe 0..5.times?

# EC: For arrays, removal methods include shift and pop, and additive methods include unshift and push.
