How do I lowercase any string then capitalize only the first letter of the word with Javascript? [duplicate]

Question

I'm not sure if I did this right, as I am pretty new to JavaScript.

But I want to lowercase any random string text and then capitalize the first letter of each word in that text.

<script>
    function capitalizeFirstLetter(string) {
        return string.charAt(0).toUpperCase() + string.slice(1);
    }

    function lowerCase(string) {
        return string.toLowerCase();
    }
</script>

Answer 1

Just change the method to

function capitalizeFirstLetter(string) 
{
  return string.charAt(0).toUpperCase() + string.slice(1).toLowerCase();
}

.toLowerCase() is appended to the last method call.

This method will make the first character uppercase and convert rest of the string to lowercase. You won't need the second method.
