How to use javascript to find the Penacchi sequence using loops

The Fibonacci Sequence, also known as the Fibonacci Sequence, is often used as an example in computer science. The sequence starts with 0 and 1, and each subsequent term is the sum of the previous two terms. Therefore, the sequence is: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89...

In JavaScript, we can implement Pebonacci through loops Calculation of sequence of numbers. The specific implementation is as follows:

function fibonacci(num){
  var num1=0,num2=1,result = [];
  for (var i = 1; i <= num; i++) {
    result.push(num1);
    var sum = num1 + num2;
    num1 = num2;
    num2 = sum;
  }
  return result;
}

In the above function, we first define two initial values ​​num1 and num2 assigned to 0 and 1 respectively, and an array result to store the results.

Then, we use a for loop to loop num times starting from 1. Each loop adds num1 to the result array, assigns the sum of num1 and num2 to num2, and then assigns num1 to num2. In the next cycle, the value of num1 is num2, and the value of num2 is num1 num2. By repeating this process, you can get the first num term of the Pebonacci sequence.

You can use the following code to test it:

console.log(fibonacci(10));

When you run this code, you can get the following results:

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

To sum up, in JavaScript, we The calculation of the Pebonacci sequence can be implemented through loops.
