well gooooooooood for you

easy to understand have a nice day

but do problems like this exist in the world of work? or just practicing logic

probably not...From experience lot of interview problems resemble leetcode or hackerrank style of problems although every site has an overlap of problems.

Nice kata!

OP solved it, closing

this should be at 6kyu

Error in test with .map:

TypeError: Cannot read property 'map' of null
at sumOfIntegersInString
at exampleTests.forEach
at Array.forEach
at describe
at /runner/frameworks/javascript/cw-2.js:152:11
at Promise._execute
at Promise._resolveFromExecutor
at new Promise
at describe

at /home/codewarrior/index.js:31:5
at Object.handleError

same error using forEach, and even for cycle, I've writter 3 variants of test, but it's not passed with error (above)

I think I've met kata like this on 6kyu

:)

Will a kata like this be used during a job interview? I'm still a beginner and often spend my time playing Codewars

every time I find an execution time out means I have to solve it with a mathematical formula
