I'm learning a bit of JavaScript, but I'm having hard time understanding the lesson on FreeCodeCamp about the recursion countdown (link).
In the lesson, there this initial example. But I'm confused on how it operates:

I am trying to complete the "Map the Debris" freecodecamp challenge https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/intermediate-algorithm-scripting/map-the-debris, and I think I've gotten it.

This is a follow up to my questions on the Arguments Optional Challenge in Freecodecamp (see below0:
I have now satisfied 5/6 conditions of the challenge, except for when the input is addTogether(2,([3])), which returns '23' as a string instead of the correct 'undefined'.
If the [3] is an array, and an array is an object, shouldn't my checkNum function work to label that as undefined? Where was the string generated?

...ANSWER
Answered 2020-Dec-15 at 19:13I am sharing my solution which is slightly different from yours. Compare it to your own. You will see that I only return inside my for loop when I get a positive match , otherwise I let the loop run. This is the biggest difference. You need to let the loop run fully and then through some mechanism keep track of the missing conditions . I have used two different variables to track the missing conditions here.
QUESTION
This regex has to match passwords that are greater than 5 characters long, do not begin with numbers, and have two consecutive digits.
All the test cases are passing the regex test.
My regex is /(?=^[a-z]+\d{2,})(?=\w{5,})/
I have to use two positive lookaheads to solve this problem to pass the tests.
But astr1on11aut is not passing the test. Why?

QUESTION
I have a question about javascript.
At first, the result of the code below is "-1 Hold", but I'm wondering why does the part where I put mark ① automatically loops with the next arguments?
I was expecting that the function processes through of it and put the result with only one argument, then goes to the next arguments. So I expected "1 Bet", "1 Bet", "-1 Hold", "0 Hold", "-1 Hold" would be output as a result.
I couldn't find explanation about this since yesterday to now.. I'd be happy if somebody helps me.

QUESTION
I just finished the FreecodeCamp.com quiz Intermediate Algorithm Scripting: Smallest Common Multiple.
The code is working fine for the test cases they give ([1, 5], [5, 1] [23, 18] and [1, 13]) but if I use a bigger range I also have to edit the code and increase the stop condition for the for-loop, and when I remove the stop condition from the loop, it gives an error.
ANSWER
Answered 2020-Jun-26 at 23:57Going to explain a little of the code; what we do first is to sort the array since it is an array of two numbers, after we sort it, we need to create a new array to store the path from the first element to the second one; we define the diference between the greatest and the smallest number in order to create a for to store the path, after we store the path; we define two functions for finding the grand common divisor and the Least Common Multiple; after that we use a reduce to get the Value of the LCM. Hope this helps you, the algorithm of the gcd is based on Euclidean Division
