fixStringCase.js

// In this Kata, you will be given a string that may have mixed uppercase and lowercase letters and your task is to convert that string to either lowercase only or uppercase only based on:

//     make as few changes as possible.
//     if the string contains equal number of uppercase and lowercase letters, convert the string to lowercase.

// For example:

// solve("coDe") = "code". Lowercase characters > uppercase. Change only the "D" to lowercase.
// solve("CODe") = "CODE". Uppercase characters > lowecase. Change only the "e" to uppercase.
// solve("coDE") = "code". Upper == lowercase. Change all to lowercase.

// More examples in test cases. Good luck!



function solve(s){
    //..
  let lower=0;
  let upper=0;
  for(let i=0;i<s.length;i++){
    if(s[i]==s[i].toUpperCase()){
    upper++
  }else{
    lower++
  }
  }
  if(lower==upper){
    return s.toLowerCase()
  }else{
    
return lower>upper?s.toLowerCase():s.toUpperCase()
  }
