What’s wrong with this JavaScript code?

Question

It’s one of the coding exercise in SoloLearn, after//your code here is my coding , which I don’t know what went wrong in the JavaScript using “switch”.

function main() {
var themeNumber = parseInt(readLine(), 10)
/*
1 - Light
2 - Dark
3 - Nocturne
4 - Terminal
5 - Indigo
*/
// Your code here

switch (themeNumber){
case 1:document.write("Light");
break;
case 2:
document.write("Dark");
break;
case 3:
document.write("Nocturne");
break;
case 4:
document.write("Terminal");
break;
default:
document.write("Indigo");}
}

The question is :

The user can choose the color theme for the browser:
1. Light
2. Dark
3. Nocturne
4. Terminal
5. Indigo

You are given a program that takes
the number as input. Complete the program so that it will output to the console the theme according to input number.

Sample Input
2

Sample Output
Dark

Answer 1

Use console.log(output);

Cheri Yan
document.write() is used to output on Web documents. console.log() outputs on js standard output console...

switch(themeNumber){

case 1:
console.log("Light");
break;

console.log("Dark");
break;
case 3:
console.log("Nocturne");
break;
case 4:
console.log("Terminal");
break;
default:
console.log("Indigo");
}

Answer 3

function main() {
var themeNumber = parseInt(readLine(), 10)
/*
1 - Light
2 - Dark
3 - Nocturne

switch(themeNumber){

case 1:
console.log("Light");
break;
case 2:
console.log("Dark");
break;
case 3:
console.log("Nocturne");
break;
case 4:
console.log("Terminal");

Answer 7

If readLine method works fine, then try by changing default case to case 5:.
Logically it may work but if input is other than 5 then it don't any output I think.
Edit : hoping code have function calling statement : main()

Answer 8

i tried using case 5, it doesnt work. in the practice output, it says “document is not defined in the main” i am just confused and wonder how to solve this problem. its a practicing problem using “javascript switch”

Answer 9

thanks a lot . ok. so instead of using “document.write” need to use “console.log” instead. thanks it works now
