Learn How to Generate Fibonacci series in C using for loop, Now!
This HTML document contains JavaScript code to generate the Fibonacci series using a while loop. Here’s an explanation of the code:
- Function Definition: The `generateFibonacciSeries` function takes a `limit` as an argument to generate Fibonacci numbers up to that limit.
- Initialization: Variables `a` and `b` are initialized to 0 and 1, respectively. An empty array `result` is created to store the Fibonacci series.
- Base Cases: The function checks if the limit is greater than or equal to 1 and 2, pushing the initial values (0 and 1) to the result array.
- While Loop: The while loop continues until the count reaches the specified limit. Inside the loop, the next Fibonacci number is calculated, added to the result array, and variables are updated accordingly.
- Return Result: The function returns the generated Fibonacci series as an array.
- Generating and Displaying Series: The code then sets the `limit` to 20 (you can change it) and calls the `generateFibonacciSeries` function. The result is displayed on the web page using `document.write`.
This code demonstrates a modular approach, encapsulating the logic within a function, making it more reusable and readable. The generated Fibonacci series is then displayed on the web page.

Output:
Fibonacci series up to 20 : 0,1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597,2584,4181 Comparison with Other Methods:
Recursion:
- Advantages: Recursion offers an elegant solution mirroring the mathematical definition of the Fibonacci series.
- Considerations: However, it may lead to stack overflow for large series due to its synchronous nature.
For Loop:
- Advantages: For loops provide explicit control over initialization, condition, and iteration, offering simplicity and efficiency.
- Considerations: The number of iterations must be predetermined, limiting flexibility.
