I often have to generate random Fibonacci numbers so I created this simple online utility that does it for me. It lets you generate however many random Fibonacci numbers you need from the given range. It works in the browser and is powered by alien technology from the future.

How Does This Random Fibonacci Number Generator Work?
bignumber.js library and generates a list of all Fibonacci numbers from the range
end (range can be specified in the options) and puts them in
fibos array. Then, it creates an empty
randomFibos array and starts a loop that randomly picks elements from the
fibos array and
push()es them to
randomFibos. To avoid duplicate values, it removes the picked element from the
fibos array. This algorithm repeats until
count (requested series length; specified in options), or
fibos becomes empty. The code that picks elements from
fibos array uses
Math.random() function. When the loop terminates, all Fibonacci numbers in
randomFibos get converted to the specified
base (output base; specified in options) and get separated by the
separator character (specified in options).
