Hi. Right now I’m just trying to recreate the Fibonacci sequence for 10, but it’s not working. I was hoping to just get a hint to point me in the right direction. Thank you.

Your code so far

/* function isOdd(value){
if (value%2 != 0)
return true;
else
return false;
} */
function sumFibs(num) {
var holder = [];
for (var i = 0; i <= num; i++){
var start = 1;
start = start + i;
holder.push(start);
}
return holder;
}
console.log(sumFibs(10));

you are doing the Fibonacci sequence wrong:
each number is the sum of the two previous numbers
so, starting with [1,1] you add 2 (1+1), then 3 (1+2), then 5 (2+3), then 8 (3+5), then 13 (5+8) and so on

you first declare start inside the loop so it will be redeclared each time the loop run and never increase, plus you use start = start + i, which is not at all how you create a Fibonacci sequence

Thanks for the feedback, I spent some time to better understand exactly what needs to happen and your examples helped. I updated to the following which I think works.

/* function isOdd(value){
if (value%2 != 0)
return true;
else
return false;
} */
function sumFibs(num) {
var holder = [1, 1];
for (var i = 0; i <= num; i++){
holder.push(holder[holder.length-2] + holder[holder.length-1]);
}
return holder;
}
console.log(sumFibs(10));

Thanks, once I was able to get the Fibonacci sequence going I was able to solve the rest

function isOdd(value){
if (value%2 != 0)
return true;
else
return false;
}
function sumFibs(num) {
var holder = [1, 1];
for (var i = 0; i <= num; i++){
var tiger = holder[holder.length-2] + holder[holder.length-1]
if (tiger <= num ){holder.push(tiger)};
var lion = holder.filter(element => isOdd(element) === true).reduce((a, b) => a + b, 0)
}
return lion;
}
console.log(sumFibs(75025));
