Basic Algorithm Scripting: Reverse a String

Your code so far

  var reverseString = function(name) {
  var revStr = ""
  for (let i = (name.length - 1); i >= 0 ; i--) {
    revStr = revStr.concat(name.charAt(i));
  }
  console.log(revStr);
}


function reverseString(str) {
  return str;
}

reverseString("hello");

Looks like a single minus sign for me instead of two minus signs.

Also you should be returning your answer not console logging it.

no i have included two minus signs in the actua code; it is just how it is displayed in the above text. however, the FCC wont accept this code.

the solution to the above challenge as provided by FCC is ```
function reverseString(str) {
return str.split(’’).reverse().join(’’);
}
``

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 easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.
