I can't join an array in a string

JavaScript
1 
function maskify(cc) {
  var string = cc.toString();
  var arr = string.split("");
 for (var i = 0; i < arr.length-4; i++){
    arr[i]="#"
 }
  
  return arr;
  var masked = arr.join(" ");
  
 }
console.log(maskify(98768777656));
console.log(masked);

// Anyone knows what am I doing wrong??

hi @alejandroperez1981,

your var masked is local scope
you can moved your console.log masked under the var masked

3

you are returning the array

everything after a return statement is not executed

maybe review where is your return statement andwhat you are returning

here is the right code, thanks a lot!.

function maskify(cc) {
var string = cc.toString();
var arr = string.split("");
for (var i = 0; i < arr.length-4; i++){
arr[i]="#"
}
var masked = arr.join(" ");
return masked;
}
console.log(maskify(98768777656));

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 (’).
