I often have to generate Lucas numbers so I created this simple online utility that does it for me. It lets you generate however many Lucas numbers you need starting from any position or value. It works in the browser and is powered by alien technology from the future.

How Does This Lucas Number Generator Work?
lucasCurrent, and initializing them to
1, which are the first two Lucas numbers. It also creates an empty
terms array that will hold the computed Lucas numbers. Each next Lucas number is calculated as a sum of
lucasCurrent. To generate
count terms (specified in options), it creates a
while() loop that keeps adding the last two Lucas values together until it finds the
start position or value (specified in options). At this moment it starts
terms.push()ing the Lucas numbers to the
terms array. The
while() loop keeps doing this until
terms.length is less than
count (sequence length; specified in options). When
count, the loop breaks and it runs base conversion code on the
terms array and calls the
terms.join(separator) function that joins all Lucas numbers by the
separator character. This function returns a string that is then printed to your screen.
