var x=0,  var y=1; var z;  fib[0] = 0; fib[1] = 1; for(i=2; i<=10; i++) {     alert(x+y);     fib[i]=x+y;     x=y;     z=y; }   I'm trying to get to generate a simple Fibonacci sequence but there no output. Can anybody let me know what's...
I need to calculate the index of a Fibonacci number with JavaScript, within the Fibonacci sequence. I need to do this without using recursion, or a loop. I found the following formula in the Math forum:     n=?log?(F?5?+12)?   and coded it in JavaScr...
I have the memoization fibonacci code and I am having trouble figuring out what the time complexity is of it:  function fibMemo(index, cache) {   cache = cache || [];   if (cache[index]) return cache[index];   else {     if (index < 3) return 1;...
function fibo() { var first,second,add; for(var i=0;i<4000;i++){     if(i === 0){         first = 1;         second = 2;     }     add = first + second;     first = second;     second = add;  }  alert(add);  }  fibo();   not working shows infinity...
Trying to get my fibonacci sequence to work using recursion but am running into the error maximum callstack exceeded.  Code:  var genFib = function(count, limit, fibArray) {   if (count === undefined || count === null) {     var count = 0;   }    if...
I've seen several posts on generating a given fibonacci sequence, such as this one. However, I can't figure out how to generate the sequence (return an array) of fibonnaci numbers for a given n using recursion.  What I have clearly doesn'...
I am trying to successfully complete this challenge on the Rosalind page. The challenge is:     Given: Positive integers n?40 and k?5.      Return: The total number of rabbit pairs that will be present after n months if we begin with 1 pair and in ea...
I've put together a generator to calculate the Fibonacci numbers/sequence. However, it's not working as I expect. I've "transpiled" it from python but I don't know what it is in my JavaScript code that doesn't fit my logic...
I am currently doing program 2 for the startup engineering course offered on coursera   I'm programming using and ubuntu instance using Amazon web services and my programming is constantly hanging. There might be something wrong with my node.js p...
Hi I was trying to come up with a function to return a fibonacci sequence, that is an array not the usual last n-th fibonacci number.  function fib(n,arr=[0]) {   if (n===0||n===1) {     arr.push(n)     return arr;   }   let arr2 = fib(n-2);   let ar...
