The first thing that jumps out at me is that you will have a space at the end of your result.

i find this solution:
function titleCase(str) {

var result = ‘’;

var words = str.split(’ ');

for (var i = 0; i < words.length; i++){

var todoAMin = words[i].toLowerCase();

var primeraMayus = todoAMin.charAt(0).toUpperCase();

var remplaza = todoAMin.replace(todoAMin.charAt(0), primeraMayus);

   result += remplaza + ' ';
        

}

var sinFinalSpace = /\s$/;

result = result.replace(sinFinalSpace, "");

return result;

}

THANKS!!!
