Day 9 is calculate the sum odd fibonacci number.
For instance, the fibonacci number of 10 will has a sequence of number from 1 to 10: 1,1,2,3,5,8
But I want to calculate the odd number only: 1,1,3,5 the result will be 10.
This is the JavaScript solution
function sumOddFibonacciNumbers(num) {
let limit = num,
prev = 0,
current = 1,
next = 0,
totalOddNumber = 0;
while(current <= limit) {
next = prev + current;
if(current % 2 === 1) {
totalOddNumber += current;
}
prev = current;
current = next;
}
return totalOddNumber;
}
