Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
let sequence = [1,2]
let sumOfEvens = 0
for(let i = 0; sequence[sequence.length-1] < 4000000; i++) {
sequence.push(sequence[sequence.length-1]+sequence[sequence.length-2])
}
for(let i = 0; i < sequence.length; i++) {
if(sequence[i] % 2 == 0) {
sumOfEvens += sequence[i]
}
}
sequence.pop(sequence[sequence.length-1])
console.log(sequence)
console.log(sumOfEvens)
