Adding number to each element in an array

Question

First of all thanks for your help...
I've tried to add numeric value to each element in the array. But the output I got was NaN. I tried using map() method to add numeric value. I also used parseInt() to get number.. But result was same. I've used the following code:

const main = () => {
let increase = parseInt(readLine(),10);
let prices = [98.99, 15.2, 20, 1026];
//your code goes here

let finalPrice = prices.map(result=(value)=>
{
return value+increase;
});
console.log(finalPrice);
}
main ();

Answer 1

Call to map was incorrect, try like this ...

let finalPrice = prices.map( value => value + increase );
