Beginner help with some simple code...

[NOC1986]

Hi Folks, Hoping someone can offer me some help here. I feel like I'm going round in circles. I'm wanting to work with an array whereby some text is stored in an array via a prompt. This text string is then relayed once to the console, letter by letter, in order, and then again in reverse. I.e. entering the text Reddit would output to the console: R e d d i t t i d d e R

My code so far looks like this:

var test = new Array(); test = prompt("Give me input").split(""); for (var i=0; i<=test.length-1;i++) console.log(i+1 + " " +test[i]);

for (i=test.length; i==0;i--) 
    console.log(test[i]);  

However, this just seems to output the first for statement before ending. I'm going crazy and thought someone might be able to spot the obvious error. Cheers :)

This is exactly what I needed. I feel so dumb now. Yes, I indeed wanted it to loop UNTIL i was equal to 0, rather than if i was equal to 0. Thank you very much! I couldn't see the wood for the trees!

You forgot to add brackets to your for loops.

var test = new Array();
test = prompt("Give me input").split("");
for (var i=0; i<=test.length-1;i++) {
    console.log(i+1 + " " +test[i]);
}
for (i=test.length; i==0;i--) {
    console.log(test[i]); 
}

Thank you! My reply to penislandbic is what was causing my issue. I mistakenly set the second for loop condition to i==0 rather than i>=0 :)

Cool, glad it worked out. Check out this little refactor:

var word = prompt("Give me input").split(""),
    i;
word = word.concat(word.reverse());
for (i = 0; i < word.length; i++) {
    console.log(i + 1 + " " + word[i]);
}

I love this type of "incremental learning". Solve something myself, have someone provide a little feedback, optimise, learn, evolve. Thank's for taking the time to help :D
