I think it is just showing that there are three ways to make a mutative change to an array, each line does the same thing.
array.push('🐴') simply adds to the end of the array array.splice(array.length, 0, '🐴') removes 0 items from the end of the array, and adds one item array[array.length] = '🐴' adds an item to a specific position, which in this case is at the end of the array
