Title Case a String without replace()

JavaScript
#1

Hello,

solved the challenge “Title Case a String” without using replace(). Please anyone let me know is it correct or have any issues.

function titleCase(str) {

    let newstr = str.toLowerCase().split("");

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

   newstr[0]=newstr[0].toUpperCase();

   if(newstr[i]==" "){

       newstr[i+1]=newstr[i+1].toUpperCase();

   }

 }

        let final = newstr.join("");

         return final;

}

titleCase("I'm a little tea pot");

Your code does work, but I would recommend not bothering with making an entire array because a String can already be iterated over like an Array as example this function would also get the job done :

function titleCase(str) {
  let s = ${str[0].toUpperCase()};

  for (let i = 1; i < str.length; i++) {
    s = ${s}${str[i - 1] === ' ' ? 
     str[i].toUpperCase() :
     str[i].toLowerCase()}
  }
  return s
}

I am using template literals which require back-ticks so unfortunately that does not work very well because back-ticks are used to write code in here.

Hi @SoumyaBandi !

Welcome to the forum!

I have added spoiler tags around your code for those who have not worked on this challenge yet.

Hi @caryaharper and @SoumyaBandi !

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
