The exercise under JAVASCRIPT called " Basic Algorithm Scripting: Title Case a Sentence". The code is down below:
function titleCase(str) {
var j, k='';
var n = str.split(' ')
var m = n.map((N) => {
j = N.charAt(0).toUpperCase() + N.slice(1).toLowerCase()
k = k + " " + j
})
console.log(k.trim())
// return str;
}
titleCase("sHoRt AnD sToUt");
if that is your whole code as you are submitting, you do not have a return statement, your function just returns undefined

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.
Thank you so much. Yes, I had to return it instead of consoling it out. Even though the code works just fine with the consoling, the question asked for a Return.
Thank you for your time.
You should be using forEach, not map. Unless you are going to use the returned array there is no point in using map.
You should really try to use more meaningful variable names.
The code inside the function works, the function itself doesn’t really work. A function is supposed to produce an output or some side-effect. Yes, logging is a side-effect but a pretty useless one unless you are writing a console application. Take the trim method you are using, how useful would it be if it just printed the trimmed string to the console but didn’t give you a new string to use?
