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?

I 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

What is wrong in my regex /(?=^[a-z]+\d{2,})(?=\w{5,})/ pattern?

Asked 2020-Nov-10 at 08:06

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?

Why does it automatically loop?

Asked 2020-Jul-01 at 15:51

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.

for-loop without stop condition?

Asked 2020-Jun-26 at 23:57

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.

Answered 2020-Jun-26 at 23:57

Going 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
