So the kata/problem was: "Simple, given a string of words, return the length of the shortest word(s)."

Example test: findShort("Bitcoin will maybe save the world")

And my solution was:

 function findShort(s){
    //   convert string to array
      const strArr = s.split(' ');
    //   loop through array and find length
      const lengthOfWords = strArr.map(string => {
        return (string.length);
    //   output length of shortest string
      return Math.min(...lengthOfWords);

    \$\begingroup\$ There are some edge cases you may want to consider: Will input always contain at least 1 word? Will input only contains letters and spaces, will there be any hyphen or punctuation marks? And what does a "word" mean in the question? What about input contains 2 continuing spaces? \$\endgroup\$

1 Answer 1


As far as implementation goes, it looks generally good to me (though arguably you should be splitting on any whitespace character, not just spaces). However I do feel that the function name (findShort) is unclear, and additionally those comments do not offer any benefit. Indeed, the second one is perhaps even misleading.
