Odin 项目的任务是使 function ‘大写’，我不知道我的回答是否合适？

Question

So I've been doing the Odin Project and I'm at functions right now and there's a task "Write a function called capitalize that takes a string and returns that string with only the first letter capitalized. Make sure that it can take strings that are lowercase, UPPERCASE or BoTh."

 <script> function capitalize(myName, myNameUpper, myNameRan) { const toUpper = "Bartek"; myName = "bartek"; myNameUpper = "BARTEK"; myNameRan = "BaRtEk"; myName, myNameUpper, myNameRan = toUpper; console.log(myName, myNameUpper, myNameRan) } capitalize(); </script>

Is my function any good? Thanks in advance for help.

<script>
     

     function capitalize(lowercase,uppercase,both ) {
     const capitalizeLower = lowercase.charAt(0).toUpperCase() + lowercase.slice(1).toLowerCase();
     const capitalizeUpper = uppercase.charAt(0).toUpperCase() + uppercase.slice(1).toLowerCase();
     const capitalizeBoth = both.charAt(0).toUpperCase() + both.slice(1).toLowerCase();
     console.log(capitalizeLower, capitalizeUpper , capitalizeBoth)
     return `${capitalizeLower} ${capitalizeUpper} ${capitalizeBoth}`
     }

     capitalize("hello","HELLO","hEllO");
    
    
     
      </script>
