Why does it not work??

Your code so far


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

change the whole string instead of a single character inside it, you can use slice to get the rest of the string for example

or, array are mutable instead
