Fibonacci Series Algorithm with printing in JavaScript Line by Line Code Example

Hello Everyone, Today, we're going to print fibonacci series text's in browser.

Let's check first fibonacci series alrorithm -

It's very simple - 

Work with Javascript for this Fibonacci Series:

function fibonacci(n) {
    let fib = [];
    for (let i = 0; i < n; i++) {
      fib.push(i < 2 ? i : fib[i - 1] + fib[i - 2]);
    }
    return fib;
}

console.log("Fibonacci Series:", fibonacci(20));

Let's solve this fibonacci series problem line by line in javascript-

1. We created a fibonacci() function
2. Initialize the fib[] array as empty. 
3. Loop throw this number. i-n
   1. If i is less than 2, i = fibonacci number
   2. If is is greater than or equal 2, fib = fib[i-1] + fib[i-2]

That's it. Basically algorithm is very simple. 

fib = fib[i-1] + fib[i-2]

Now, let's make a demo to show this fibonacci series in browser - 

 So, check this fibonacci series problem in javascript and let me know if any more issues happen with Fibonacci series problem of javascript.
