JavaScript Kata #23: Returning Strings

If you missed the introductory post, it's here. For a list of previously solved katas, please refer to the bottom of this page.

If this is your first time seeing my post, please note - these katas are probably randomly assigned per user so please don't go into Codewars thinking we will have exactly the same user experience, I am just posting these in the order that I got them.

Kata #23

DESCRIPTION:

Make a function that will return a greeting statement that uses an input; your program should return, "Hello, <name> how are you doing today?".

[Make sure you type the exact thing I wrote or the program may not execute properly]

Starting code:

function greet(name){
  //your code here
}

My attempt:

const greet = name => `Hello, ${name} how are you doing today?`

Rank #1 in 'Best Practice':

function greet(name){
  return `Hello, ${name} how are you doing today?`;
}

Rank #2:

const greet = name => `Hello, ${name} how are you doing today?`;

Rank #3:

// Return a greeting string
function greet(name) {
  return "Hello, " + name + " how are you doing today?";
}

And brace yourself for another troll in the form of user rabbit_binary7 at rank #4:

function greet(name) {
  return `\x48\x65\x6c\x6c\x6f\x2c\x20${name}\x20\x68\x6f\x77\x20\x61\x72\x65\x20\x79\x6f\x75\x20\x64\x6f\x69\x6e\x67\x20\x74\x6f\x64\x61\x79\x3f`
}

Here is a converter I found to figure out that the codes are hexadecimal, and that it's quite ironic for them because the username is literally rabbit_binary7. I'm guessing that person has so much time on their hands to type all that out if it was typed one by one. There are "text to hex" converters I found online but didn't see one that provides the escaping (\x) for JavaScript, so maybe they made their own (I think easy enough if they added to this pre-made code). The Internet is truly such a strange place.

That's it for Kata #23, stay tuned for more katas to be solved!
