Fibonacci series in JavaScript

The generateFibonacciSeries function takes a parameter n which represents the number of Fibonacci numbers to generate. Example of how you can generate a Fibonacci series in JavaScript using a loop:

function generateFibonacciSeries(n) {
  const fibonacciSeries = [0, 1]; // Initial values of Fibonacci series

  for (let i = 2; i < n; i++) {
    const nextNumber = fibonacciSeries[i - 1] + fibonacciSeries[i - 2];
    fibonacciSeries.push(nextNumber);
  }

  return fibonacciSeries;
}

const n = 10; // Number of Fibonacci numbers to generate
const fibonacciSeries = generateFibonacciSeries(n);
console.log(fibonacciSeries);

In this example, the generateFibonacciSeries function takes a parameter n which represents the number of Fibonacci numbers to generate. It initializes the fibonacciSeries array with the initial values [0, 1].

Then, using a for loop starting from index 2, it calculates the next Fibonacci number by adding the previous two numbers and pushes it into the fibonacciSeries array.

After the loop finishes, the function returns the fibonacciSeries array.

In the code snippet, we set n to 10 to generate the first 10 Fibonacci numbers. You can change the value of n to generate a different number of Fibonacci numbers.

Finally, we log the fibonacciSeries array to the console to see the result.

When you run the code, you will get the following output:

[0, 1, 1, 2, 3, 5, 8, 13, 21, 34]

This is the Fibonacci series with the first 10 numbers.
