Why this code not working in Sololearn?

Question

function main(increase) {
const prices = [98.99, 15.2, 20, 1026];

for (i = 0; i < prices.length; i++) {
prices[i] = prices[i] + increase;
}

return console.log(prices);
};

main(Number(prompt()));

Sololearn JavaScript projects are running on Node JS so prompt will not work here.

You have to use readLine() function

Also you are returning console.log which is a default function in JS

You have to return array. But actually you don't have to return anything just print prices

If you print using console.log then why you need to return that.

Do this:

function main() {
const prices = [98.99, 15.2, 20, 1026];

var increase = parseInt(readLine());

for (var i = 0; i < prices.length; i++) {
prices[i] = prices[i] + increase;
}

console.log(prices);
};

//main(Number(prompt()));

Because you have wrongly returned value and also no need to call main function

You didn't declared i also

This code working correctrly in VS Code.
