Outputs a number in the fibbonacci sequence in the console. Read about the fibbonacci sequence at https://en.wikipedia.org/wiki/Fibonacci_number

Fibbonacci Sequence.js

var calc = function (amount) {
  var a = 1   //change the two variables to get a different fibbonacci sequence
  var b = 1
  for(var i = 0; i < amount; i++) {
    var i = a+b
    b = a
    a = i
  }
  console.log(a) //outputs the 'amount' number in the fibbonacci sequence.
}
calc(100) //how many numbers you want to produce
