Generate Fibonacci Sequence Up to a Certain Number in JavaScript | Learn JavaScript & Algorithms

Generate fibonacci sequence up to a certain number in javascript. How to display fibonacci numbers sequence to a specified limit, or fibonacci numbers not exceeding a specified "number"? A series of numbers in which each number is the sum of the two preceding numbers is fibonacci series of numbers.

To get fibonacci numbers series to a specified limit here is what we have to do. Define a JavaScript function which takes an input parameter "number". It will return an array of fibonacci numbers not exceeding "number".

Initialize two variables "n1" and "n2" with 0 and 1 respectively. Initialize a variable "next" with the sum of "n1" and "n2". Initialize an empty array "sequence". Use a while loop that continues until "next" is less than or equal to the "number".

In each iteration, add the value of "next" to the "sequence" array. Replace "n1" with "n2". Replace "n2" with "next". Calculate the next fibonacci number by adding "n1" and "n2". Return the "sequence" array.

Call the function with a number as argument. It will return an array of fibonacci numbers not exceeding this number that we specified here. So this is how we can display 'fibonacci numbers sequence' to a specified limit.
