JavaScript

Follow the instructions bellow for a good rate

Create a program that will display the result of three functions: a) sum the elements from the Fibonacci sequence b) divide them by randomly generated number c) calculate factorial from the rounded result of previous operation

Functions should be stored in one, separate file. The main program should run from the app.js. Finally, a user should provide input for two variables - the number of Fibonacci items and the number responsible for the range of the randomly generated number from point b)

-----------------------------------------------------------------

Code for app.js is showen bellow:

app.js:

function calculateFibonacci(num) { var a = 1, b = 0, temp;

while (num >= 0) { temp = a; a = a + b; b = temp; num--; }

return b; }

function displayFibonacci(s) { var result = ""; for (i = s; i > 0; i--) { result += calculateFibonacci(i) + ", "; } return result.substring(0, result.length - 2); }

console.log(displayFibonacci(21));

--------------------------------------------------------------------

Output in Console:
