Basic Algorithm Scripting - Title Case a Sentence

JavaScript
1

Tell us what’s happening:
why is this method not working perfectly?

Your code so far

const titleCase = function(sentence){
  
    let str = sentence.split(" ")
    for (let i = 0; i < str.length; i++){
      
      str[i]= str[i][0].toUpperCase() + str[i].substring(1);
    }
   return str.join(' ')

}

titleCase("tolu goes to school");

Have you tried running the failing test to see what happens?

const titleCase = function(sentence){
  let str = sentence.split(" "); // Does this need let?
  for (let i = 0; i < str.length; i++) {
    str[i] = str[i][0].toUpperCase() + str[i].substring(1);
  }
  return str.join(' ');
}

console.log(titleCase("sHoRt AnD sToUt"));

Yes, I have seen the error, it requires I first of all make the sentence lowercase. Then proceed to make the first word of each sentence uppercase

I have gotten the answer , all I needed to was to add a lowercase() to the substring(),

const titleCase = function(sentence){
  
    let str = sentence.split(" ")
    for (let i = 0; i < str.length; i++){
      str[i].toLowerCase()
      str[i]= str[i][0].toUpperCase() + str[i].substring(1).toLowerCase();
    }
   return str.join(' ')

}

titleCase("tolu goes to school");

@JeremyLT , Why do you think the let is not needed?

Generally, you should use const wherever possible
