Tell us what’s happening:
Please help.
Whenever I run the test, I get it wrong but the console shows the right answers without the quotation marks. Would be much grateful

Your code so far


function reverseString(str) {
let arr = [];
let strarr = str.split("");
for (let i = strarr.length - 1; i >= 0; i --) {
arr.push(strarr[i]);
}
console.log(arr.join(""));
}

reverseString("Greetings from Earth");

Thank you very much, but whenever I run it I do not get undefined. Would try the return statement though.

#4

to have printed to the console what the function return you need to put the function call in a console.log:


console.log(reverseString("Greetings from Earth"));

Thanks :+1: @ilenia, it worked. I think i had a wrong view on console.log() and return.
