fibonacci series in javascript code example

Example 1: fibonacci javascript

function Fibonacci(num){
	var before = 0;
	var actual = 1;
	var next = 1;

	for(let i = 0; i < num; i++){
		console.log(next)
		before = actual + next;
		actual = next
		next = before
	}
}

Fibonacci(100);

Example 2: javascript fibonacci

function fibonacci(n) {
   return n < 1 ? 0
        : n <= 2 ? 1
        : fibonacci(n - 1) + fibonacci(n - 2);
}

console.log(fibonacci(4));

Example 3: js fibonacci sequence

// number fibonnaci to array format
function fibonacci(nums) {
  
  let fib = [0, 1];
  let data = [];
  
  for(let i = 2; i <= nums; i++) {
    fib[i] = fib[i - 1] + fib[i - 2]; 
    data.push(fib[i]);
  }
  
  return data;
}

Example 4: fibonacci javascript

function Fibonacci(valor){
	var anterior = 0;
	var atual = 1;
	var proximo = 1;

	for(let i = 0; i < valor; i++){
		console.log(proximo)
		anterior = atual + proximo;
		atual = proximo
		proximo = anterior
	}
}

Fibonacci(100);

Example 5: recursive function for fibonacci series in java javascript

var fib = function(n) {
  if (n === 1) {
    return [0, 1];
  } else {
    var arr = fib(n - 1);
    arr.push(arr[arr.length - 1] + arr[arr.length - 2]);
    return arr;
  }
};

console.log(fib(8));

Example 6: fibonacci javascript

function fibonacci(num){ 
	var num1=0; 
	var num2=1; 
	var sum; 
	var i=0; 
	for (i = 0; i < num; i++){ 
		sum=num1+num2; 
		num1=num2; 
		num2=sum; 
	} 
	return num2; 
}
