fibonacci recursive in javascript code example
Example 1: javascript recursive fibonacci
function recursiveFibonacci(n){
if(n === 0) return 0
if(n === 1) return 1
return recursiveFibonacci(n - 2) + recursiveFibonacci(n - 1);
}
recursiveFibonacci(6)
function iterativeFibonacci(n) {
if (n === 0) return 0;
if (n === 1) return 1;
let previous = 0;
let current = 1;
for (let i = n; i > 1; i--) {
let next = previous + current;
previous = current;
current = next;
}
return current;
}
iterativeFibonacci(6)
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: javascript fibonacci example
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: 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 5: fibonacci recursion javascript
function fibonacci(n) {
if (n < 2){
return 1;
}else{
return fibonacci(n-2) + fibonacci(n-1);
}
}
console.log(fibonacci(7));
Example 6: 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(2));
