I've recently solved this problem, what I ended up using for this purpose is a regex.

Single line solution

const result = "SeLamAT PAGi semua halOo".replace(/(^\w{1})|(\s+\w{1})/g, letter => letter.toUpperCase())

Alternative solution

function titleCase(input) {
   const splittedInput = input.toLowerCase().split(' ');
   for (const i = 0; i < splittedInput.length; i++) {
       splittedInput[i] = splittedInput[i].charAt(0).toUpperCase() + splittedInput[i].substring(1);     
   }
   return splittedInput.join(' '); 
}

const result = titleCase("SeLamAT PAGi semua halOo");
console.log(result);

  • @achmadrobbi notice that the replace method is not changing the string, you've to assign the result to a variable. I've updated the code so that this behavior would be more clear. – desoss Feb 08 '22 at 16:49
