Javascript algorithms Reverse a string

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 --) {

reverseString("Greetings from Earth");

Challenge: Reverse a String

Link to the challenge:

your function always return undefined



because it doesn’t have a return statement.


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

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.
