- Read the "Challenge description" below.
- Make changes to the challenge.js file.
- Commit your changes.
- Wait for the result of the "GitHub Classroom Workflow" action. If it is green - congratulations, you solved this challenge! If not - try again!
- You can watch an example of how to solve a challenge in the video linked in the theoretical lesson preceding this challenge.
You will be given a positive integer number . Fill in the method sum so that it adds up all the positive integers up to number and returns the sum. For example, when given 4 it should return 10 (4+3+2+1).
While there are other ways to solve this challenge, you should use recursion to get the sum.
console.log(sum(4))
// => (4 + 3 + 2 + 1) = 10
console.log(sum(10))
// => 55Get stuck and need some hint? Check this link: https://gitlab.com/microverse/guides/coding_challenges/hints/blob/master/challenges/recursion/basic-recursion.md
