Hello Friends,

Now let's see example of how to get fibonacci series example. We will check how to get fibonacci series. This is a short guide on get fibonacci series in javascript. Let's get started with how to get fibonacci series in javascript.

Here i will give you many example how to get fibonacci series using javascript.

**Example : 1**

<html> <head> <title>How To Get Fibonacci Series In JavaScript Example - MyWebtuts.com</title> </head> <body> <h3>How To Get Fibonacci Series In JavaScript Example - MyWebtuts.com</h3> <script> var a1 = 0, a2 = 1, a_num, i; var num = parseInt (prompt (" Enter the limit for Fibonacci Series :")); document.write( "Fibonacci Series : "); for ( i = 1; i <= num; i++) { document.write (" <br> " + a1); a_num = a1 + a2; a1 = a2; a2 = a_num; } </script> </body> </html>

**Output :**

Enter the limit for Fibonacci Series : 10 Fibonacci Series : 0 1 1 2 3 5 8 13 21 34

**Example : 2**

<html> <head> <title>How To Get Fibonacci Series In JavaScript Example - MyWebtuts.com</title> </head> <body> <h3>How To Get Fibonacci Series In JavaScript Example - MyWebtuts.com</h3> <script> var number = 8; var a1 = 0, a2 = 1; var n_num = 0; document.write( " Fibonacci series of the number 8 : " + "<br>") for (i = 1; i < number; i++) { if ( i <= 1) n_num = i; else { n_num = a1 + a2; a1 = a2; a2 = n_num; } document.write( " Add " + a1 + " and " + n_num + " = " + (a1 + a2) + "<br>" ); } </script> </body> </html>

**Output :**

Fibonacci series of the number 8 : Add 0 and 1 = 1 Add 1 and 1 = 2 Add 1 and 2 = 3 Add 2 and 3 = 5 Add 3 and 5 = 8 Add 5 and 8 = 13 Add 8 and 13 = 21
